Demos in Fiji
While taking their Far from Frozen climate change showcase to Fiji, the Otago Museum science team took every chance to share some photonics-based demos with the students that came along.
The students were great and loved exploring properties of light using diffraction glasses, lasers and IR cameras as well as exploring hidden worlds under UV light.
Over two weeks the team spent time in Suva, Rakiraki and Lautoka, taking science to over 1,000 students who otherwise wouldn't have such an opportunity.

Jon Wells and I hosted the 20th International Conference on Dynamical Processes in Excited States of Solids (DPC19) at the Chateau on the Park, Christchurch, in the week of August 26-30. Jon and I handled local organisation and Jevon Longdell (Otago) was the Programme Chair. Dodd-Walls was a major sponsor.
This journey to this event began three years ago, at the previous DPC conference in Paris, where Jon Wells, Roger Reeves, Jevon Longdell, and I put together the bid that was accepted by the International Committee. We locked in the venue about 15 months ago, and waited to see what numbers we would have. Clearly, it’s hard to get a lot of people to fly all the way from Europe, so our meeting was much smaller than Paris, but several participants commented favourably on the standard of work presented, and the friendly feel of the meeting.
Of 93 scientific participants 73 were from overseas (26 from China). There were 34 students (23 from overseas). I was particularly pleased that we had a large number of overseas students. 11 of the Chinese participants arrived on the direct flight from Guangzhou on the Sunday evening. That connection certainly makes travel to Christchurch from China very efficient, and they just fitted into the 11-seat shuttle that I ordered for them!
Many of the presentations were on Quantum Information and Nanoparticle applications, which was highly relevant to the Canterbury and Otago students. This was an excellent opportunity for them to discuss their work with prominent people in those fields. Jamin Martin from Canterbury, and Peter Barnett, from Otago won two of the six poster prizes. The winners had a good geographical spread: New Zealand, China, Poland, and Australia.
DPC was previously run in Christchurch in 2003, Chaired by Roger Reeves. The participants, and the subject areas, have changed dramatically since then. Particularly notable is the large increase in Chinese participants (and less Japanese, European and American). The next conference is in 2022 in Wrocław, Poland.
The conference venue was very congenial and efficient. Our overseas participants appreciated the excursion that took in Rutherford’s Den (Old University site), some of the city sights, a winery, and a quick stop at the current UC campus.
We were ably assisted by our UC and Otago students and postdocs, and were pleased to have UC Deputy Vice Chancellor (Research) Ian Wright opening the conference, and Head of School of Physical and Chemical Sciences Rudi Marquez at the Banquet. We are grateful to all our helpers, and to the UC staff who helped with web pages, purchasing, and printing. Also, of course, our sponsors: Dodd-Walls, UC, Bruker, and Elsevier.

The International Conference on Laser Spectroscopy is a biennial conference concerning developments and applications of precision measurement and control in atomic systems. The 24th ICOLS was held in Queenstown from July 8th until 12th, and attracted about 170 participants from around the world.
Highlights included the stunning line up of plenary speakers, including Professors Eric Cornell (Nobel Prize 2001), Ana-Maria Rey, Tilman Pfau, Jun Ye, and Holger Mueller. An array of invited and hot topic talks (including our very own Assoc. Prof. Niels Kjaergaard and Scott Parkins) highlighted research at the cutting edge of the field. The conference was well attended by Dodd-Walls Members, with many of the approximately 150 poster presentations showcasing our research.
Two memorial sessions celebrated the contributions of two key members of the ICOLS community who recently died: Our own Prof. Howard Carmichael spoke on the contributions of Professor Roy Glauber (Nobel Prize 2005), who had deep connections to the quantum optics community in New Zealand. Prof. Ken Baldwin spoke on the life and contributions of Professor Wim Vassen, followed by an impressive talk from Yuri van der Werf on recent research in the Vassen group. Prof. Vassen's work was on Helium spectroscopy and the production of ultra-cold Helium gases, and included collaborations with Dr Maarten Hoogerland.
Participants enjoyed a fantastic week in Queenstown including a superb conference dinner at Walter Peak Station. It was quite amazing to see so many quantum physicists in awe of the steam engines on the TSS Earnslaw used to ferry us over to the station. Huge credit to our Prof. David Hutchinson who made the bid to hold ICOLS in New Zealand 2 years ago, and who chaired the organizing committee.
At the conclusion of the meeting it was announced that ICOLS-2021 will be in Colorado organized by a team from Boulder.

Over 300 people (290 from overseas and from 34 countries) collected in Auckland the week of 8 July 2019 to discuss the latest developments and applications of vibrational spectroscopy.
The tenth International Conference on Advanced Vibrational Spectroscopy (ICAVS10) was enjoyed by all due to the excellent and varied programme. There was a series of plenary lectures that covered a wide range of topics, including the application of near infrared spectroscopy in food industries, plasmon-enhanced Raman spectroscopy, developing an infrared-based device for clinical application, and nonlinear vibrational spectroscopy for the study of interfaces. The range of oral and poster presentations was even more extensive.
The exhibition space highlighted the latest technology available in vibrational spectroscopy, including a quantum cascade laser based mid-infrared imaging system and frequency comb-based IR spectrometer.
At ICAVS10 we tried to make sure there were plenty of opportunities for students and early career researchers to network and embrace the conference experience, for example, several students were given the chance to chair a session, and there was a sponsored student pub night.
The conference was a success and many of the attendees will, no doubt, see each other at the next ICAVS in Krakow in 2021.

Eric Cornell is an American physicist who, with Carl Wieman and Wolfgang Ketterle, won the Nobel Prize for Physics in 2001 for creating a new ultracold state of matter, the so-called Bose-Einstein condensate (BEC).
The existence of the condensate had been predicted by Albert Eistein, among others, and Cornell had been searching for it for over 10 years before his breakthough - which was discovering that chilling and slowing atoms caused them to merge into a single entity. Eric Cornell has been in New Zealand to attend the 24th International Conference On Laser Spectroscopy (ICOLS), hosted by the Dodd-Walls Centre, New Zealand's national research group for photonic and quantum technologies, which combines top scientists from across the country and is based at the University of Otago.
Tuesday 9th July 2019
A group of leading scientists, including the world's best atomic clockmaker and a Nobel Prize winner, are spending time in Queenstown this week. The 24th International Conference On Laser Spectroscopy, which began yesterday and runs until July 12, includes 170 attendees from 17 countries.
Attendees will discuss how they use laser light to make increasingly precise measurements of the world around them - such things as time, mass and gravity. The conference is hosted by the Dodd-Walls Centre, New Zealand's national research group for photonic and quantum technologies, which is based at the University of Otago. Dodd-Walls Centre director David Hutchinson said it was an honour to be chosen to host the conference. New Zealand was a world leader in quantum physics, the science of the ultra-small. "If we could only see on the scale of metres and seconds, we never would have discovered that quantum physics exists at all. "That discovery was made possible by better measuring techniques that revealed the nanoscale." Prof Hutchinson said it was the 24th conference since 1973, and only the second to be held in the southern hemisphere. The conference was traditionally held in a resort and it was a "real honour to have it here in Queenstown", he said.
The star line-up of speakers includes Eric Cornell, who won the Nobel Prize for creating a new state of matter in the lab, throwing the gates open to explore the quantum realm. Known as a Bose Einstein Condensate, this quantum state of matter makes it possible to observe and play around with quantum effects large enough to see and measure in the lab. Mr Cornell will also be holding a public lecture on Monday at Otago Museum, "Investigating Supersymmetry". Other conference speakers include the world's best clockmaker Jun Ye, from the University of Colorado in Boulder, top expat Kiwi clock builder Murray Barrett, and Howard Carmichael, billed as New Zealand's best-known scientist in the field. Mr Hutchinson said the clock-makers were working on atomic clocks, using caesium to define a second. Clocks could be made even more accurate using other elements, and soon the definition of a second would probably change, Prof Hutchinson said.
Monday 8th July 2019
The world's top clockmakers are gathering in Queenstown this week, to discuss quantum science.
These scientists are pushing to make the measurement of time more precise. That may sound unnecessary but it's crucial to understanding the quantum world.
Murray Barrett is an ex-Otago student who know works at the Centre of Quantum Technologies in Singapore. He's in the country for the conference hosted by the Dodd-Walls Centre.

MIGHTY SMALL MIGHTY BRIGHT - TODAY’S SCIENCE, TOMORROW’S TECHNOLOGY
Lasers, rainbows and magnetic nanoparticles… it’s just some of the extraordinary science that is at your fingertips in the Mighty Small Mighty Bright exhibition now on at MOTAT
MOTAT has partnered with New Zealand’s leading scientific research institutes the MacDiarmid Institute and the Dodd Walls Centre, as well as Otago Museum to develop a touring science exhibition that will demystify the fascinating world of photonics, advanced materials and nanotechnology.
“MOTAT is known as a place of ideas and exploration and so it has been a perfect fit and a professional pleasure to work with all the partners to develop Mighty Small Mighty Bright” says MOTAT exhibitions manager Rebecca Britt.
“MOTAT brought its community outreach and exhibition design skills to the partnership because we believe the achievements of our science community should be shared, celebrated and demystified.
We want the next generation of young science superstars, who visit us at MOTAT every day, to see that they too can change the world with their discoveries, from right here in New Zealand.”
Mighty Small Mighty Bright is open to the public at MOTAT’s M1 Great North Rd location and will remain on show through until September before embarking on a tour to other destinations around Aotearoa.
The exhibition has been designed with families in mind and will be particularly attractive to children aged 8 and above.“The Dodd-Walls Centre is committed to making science more accessible for all Kiwis and by partnering with the museum sector we make this happen much more effectively than the traditional model of talks or lectures” explains Professor David Hutchinson, Director of the Dodd-Walls Centre.
“Mighty Small Mighty Bright brings science to your community, your families, and makes it fun and hands- on. We hope all visitors will leave having learnt a little and having been inspired a lot. Science is for everyone. Enjoy it!”
MacDiarmid Institute Co-Directors Associate Professor Nicola Gaston and Professor Justin Hodgkiss said that partnering with MOTAT had enabled the MacDiarmid Institute to showcase just how vital materials science was to the world around us, from flexible solar panels and superconductors, to anti-bacterial silver particles.
“Mighty Small Mighty Bright shows how science translates from the lab to the marketplace, with real-life examples of hi-tech materials science underpinning industry in New Zealand.
We’re always keen to find new ways to inspire young people to keep on with science and be part of the hi-tech economy.”

Red Sock Award for DWC Member
DWC member Andrus Giraldo was one of the seven winners of the famous Red Sock Award for best poster at the biennial SIAM Conference on Applied Dynamical Systems, held with over 1000 participants in Snowbird, Utah last week. The award consists of a pair of red socks and a cash prize, handed over in person by Prof James A Yorke (the University of Maryland, famous for his paper “Period three implies Chaos”), who wears only red socks himself.
Nathan Pages manages to capture part of the award ceremony.
The only other time that we had such a success for the University of Auckland was in 2009 when Ph.D. student Emily Harvey won a Red Sock Award (see the report in the July 2009 issue of DSWeb Magazine. Claire Postlethwaite has also won a Red Sock Award, but it was in 2003, well before she became affiliated with the University of Auckland (this was reported in the first-ever DSWeb Magazine issue from October that year).

Quantum Physicists shining new light on Cave Art
Leslie Van Gelder, a well-known American-born archeologist has been working with Dr Harald Schwefel, and other physicists at Otago University to develop a lamp that mimics the flickering torch light that paleolithic cave artists worked by many thousands of years ago. The lamps will help Leslie and other archeologists reveal intimate details of these ancient people.
The collaboration brings together quantum physicists and archeologists with indigenous Australian land-owners, deer stalkers, artists, ancient DNA specialists, university students and a product designer. The story shows the unexpected ways cutting edge science research can enrich cultural understanding and heritage. It speaks to a willingness and generosity in the New Zealand science community to try something different and help each other out.
Tens of thousands of years ago ancient people of Europe and Australia trekked deep into caves by torchlight creating images on the walls of horses, bison, reindeer and stencil outlines of their own hands. In the flickering firelight of their ancient lamps, the figures would appear to move. The shadows on the curved cave walls gave them an illusion of volume and life and the colours appeared inky-rich and deep. This was how the ancient artists would have seen their work. But in the past few decades open flames have been banned in heritage cave sights and the LED lights that replaced them have taken away much of the mystery.
“The flat grey and white light of the torches made with LED’s produce an almost clinical light and rob the animals of their warm colors and their shadows,” Leslie says.
It was a conversation with a cave guide in Europe in 2016 that gave Leslie the idea for creating the new lamps. Not only could this give a more authentic experience of the caves. It would also help to answer important research questions.
“As a researcher I have been drawn to questions of light for the last decade,” Leslie says. “These new lamps will help us to explore questions of how people moved through the caves and drew the on the walls... Some of the images are found high up in hard to reach places. The artists would have had to climb five metres up a wall or stalactite to reach them, which would require both hands. So someone else must have held the light. I have a soft spot for the people in the shadows who might not have made the drawings themselves but allowed someone else to by holding their light.”
Leslie returned to Glenorchy in New Zealand where she lives, with a mission to find a more authentic lighting solution. The first step was to try to create an authentic copy of the ancient lamps to work out what qualities of the light the lamps needed to mimic. She sourced animal fat from local deerstalkers and a butcher to mimic the reindeer and auroch tallow used in ancient lamps. She worked with a local sculptor to fashion a stone base using primitive tools.
To create a modern equivalent she needed some physicists. This is where the Dodd-Walls Centre comes in. This national centre of collaborative research brings together scientists across the country doing world-leading research in light and quantum science. Leslie discovered the Director of the Dodd-Walls Centre, Professor David Hutchinson while searching the University of Otago website.
“He looked approachable and was leading an interdisciplinary centre that focuses on light,” says Leslie. “So I wrote to him. He replied straight away and said he could help. I wasn’t expecting it to be that easy!”
Professor Hutchinson put Leslie in touch with Dr Schwefel, a Principal Investigator with the Dodd-Walls Centre, also based at the University of Otago. In his core research Dr Schwefel develops world-leading components for incredibly powerful quantum computers. He recently published a paper in the prestigious scientific journal Nature announcing his invention of a device that could revolutionise internet efficiency and speed. So this project came out of left field.
“It was really great to see how we could use our knowledge of light and its spectral properties to provide help for the archeology community” says Dr Schwefel. “Once we identified what we wanted to achieve in terms of the flickering pattern and spectrum, then it was pretty straight-forward to devise a candle-like structure that had the correct flickering pattern.”
Dr Schwefel brought in two PhD students as consultants and a summer student Timothy Marshall, who worked with the Dodd-Walls Centre Industry manager, Luke Taylor to create the product. The Dodd-Walls Centre funded the whole project.
“They asked me for a Christmas wish list of all the things I wanted the lamp to do,” Leslie explains. “It’s incredibly hard to find funding in the archaeology community,” Leslie says. “This was an amazing gift to have their support.”
In the summer of 2018-19, Timothy worked with Dr Schwefel and Luke Taylor to produce six hand held lamps that Leslie could take as prototypes to a cave in Australia where she was working in March.
“Working to my ‘wish list’ for color, intensity, and flicker, their team did an amazing job and a week before I left, a suitcase arrived for me in Glenorchy that had 6 beautiful lamps. The glass for them had been hand blown by the chemistry department’s glassblower, the bodies of each lamp mimicked stone from different parts of the world and the mechanism were three LED lights colored to the sodium line they had discovered in their light spectrum analysis. Luke and Timothy had done a series of experiments with wind and wick length to produce a series of potential flicker patterns so the lamps in the end had 13 different intensity and flicker pattern that I could change with just the flick of a button. Magic!”
There was an almost audible silence when the team of scientists, archeologists and traditional indigenous land owners entered the cave in Australia that Leslie had lit using the new lamps.
“It was a very moving experience to see the cave in the flickering warm light of the ‘paleo-lamps,” Leslie says.
This is just the beginning of the collaboration. Having discovered ancient fire-sticks in the Australian cave, Leslie will work with Harald and the team alongside the local Aboriginal community to develop a new lamp to mimic its light.
Even though the project was tangent to Harald’s core focus on quantum computing and photonics, it provided an excellent opportunity to contribute to a new field. It also gave the students valuable experience of developing a product and getting it to market with a deadline.
According to Leslie the archeology community have been impressed and inspired by the project. presented the story at a specialist conference on rock art.
“I presented the story at a rock art conference recently,” She says. “Some archeologists told me it restored their faith in archeology. There is a real respect and interest in the perspective from another field like physics.”
Next spring Leslie will be returning to Europe to continue her cave research there. She will be taking with her a box of the new lamps as a gift from the Dodd-Walls Centre.
“I look forward to seeing what we might be able to see for the first time in the shadows and flickering lights of our lamps,” Leslie says.

Thursday 18 April 2019
A team of University of Otago/ Dodd-Walls Centre scientists have created a novel device that could enable the next generation of faster more energy efficient internet. Their breakthrough results have been published in the world’s premiere scientific journal Nature this morning.
The internet is one of the single biggest consumers of power in the world. With data capacity expected to double every year and the physical infrastructure used to encode and process data reaching its limits there is huge pressure to find new solutions to increase the speed and capacity of the internet.
Principal Investigator Dr Harald Schwefel and Dr Madhuri Kumari’s research has found an answer. They have created a device called a microresonator optical frequency comb made out of a tiny disc of crystal. The device transforms a single colour of laser light into a rainbow of 160 different frequencies - each beam totally in sync with each other and perfectly stable. One such device could replace hundreds of power-consuming lasers currently used to encode and send data around the world.
The work was born out of Dr Schwefel’s previous research at the prestigious Max Planck Institute in Germany and his collaboration with Dr Alfredo Rueda who did some of the preliminary research.
The internet is powered by lasers. Every email, cell phone call and website visit is encoded into data and sent around the world by laser light. In order to cram more data down a single optical fibre the information is split into different frequencies of light that can be transmitted in parallel.
Dr Kumari says the current infrastructure is struggling to cope with demand as internet consumption increases significantly.
“Lasers only emit one colour at a time. What this means is that, if your application requires many different colours at once, you need many lasers. All of them cost money and consume energy. The idea of these new frequency combs is that you launch one colour into the microresonator a whole range of new colours comes out,” Dr Kumari says.
“It’s a really cool energy saving scheme,” says Dr Schwefel, “It replaces a whole rack of lasers with small energy efficient device.”
He expects the devices to be incorporated in sub-oceanic landing stations where all the information from land based fibres is crammed into the few sub-oceanic fibres available in less than a decade, perhaps within a few years.
“To develop the device for the telecommunications industry we will need to start working with major telecommunications companies,” Dr Schwefel explains. “We have started the process by collaborating with a New Zealand-based optical technology company.”
This breakthrough is the first milestone in a government funded collaboration between scientists at the University of Otago and the University of Auckland who are part of the Dodd-Walls Centre for Quantum and Photonic Technologies - a virtual organisation gathering New Zealand’s top researchers working in the fields of light and quantum science. The research project has been awarded nearly one million dollars of Marsden Fund money to develop and test the potential of microresonator frequency combs.
The optical frequency combs are based on a very unusual optical effect that happens when the intensity of light builds up to extremely high levels. You send a single colour of visible light into the crystal disc along with a microwave signal and because the crystal disc is such high quality, the light and microwave radiation gets trapped inside. The light and microwave radiation keeps pouring in and bouncing around and around inside the crystal. In most situations light never changes colour but in this case the intensity becomes so high that the light and the microwave radiation start merging and making different colours. The phenomenon is known as a non-linear effect and it has taken the team many years to optimise.
The only other group in the world making devices of competing quality is a collaboration from Harvard and Stanford Universities in the US, also published in this month’s Nature, but currently Drs Schwefel and Kumari hold the record for the most efficient device. Essentially this means that their crystals don’t leak any light. The trick is to have an extremely high quality crystal. Harald’s group are a world experts in crafting crystal discs in his University of Otago lab.
The internet is just one of the possible applications for the new optical frequency combs. Another use is high-precision spectroscopy — using laser light to study and identify the chemical composition, properties and structure of materials including diseases, explosives and chemicals. Dr Kumari’s next mission will be to explore this application amongst other possibilities.
“This is a very very exciting project to be working on,” says Dr Kumari. “Optical frequency combs have literally revolutionised every field of applications they have touched. You can use them for vibrational spectroscopy, distance measurement, telecommunications. I’m looking forward to seeing how we can use ours.”

Congratulations to Dr Simon Poole and his team at Finisar Corporation (NASDAQ: FNSR) for winning the Australian Prime Minister Prize for Innovation for 2018. Simon is the Chair of the Dodd-Walls Centre’s Industry Advisory Board.
Simon and his team have invented technologies that make global internet connections faster.
The global internet we rely on is carried by optical fibres that link continents, countries and cities. The speed and volume of internet traffic was limited by the need to convert data from light to electrical signals for switching and processing. To tackle the speed problem, the Finisar team created light-bending switches using prisms, liquid crystals and silicon, which have dramatically improved the capacity and reliability of the internet. One switch can handle one million simultaneous high definition streaming videos.
The team are now working to boost the capacity of their devices further to meet the demands of 5G and the Internet-of-Things.

Monday 14 May 2018
When the Auckland harbour bridge lights up at 12.01 am on Wednesday 16th May, it will signal the beginning of world-wide celebrations for the International Day of Light. The six-minute Vector light and sound show will depict light and energy from the earliest origins of human settlement in New Zealand, through the Maori creation story, to the possibilities for a future world harnessing the true potential of energy and light technologies. Chair of the New Zealand Committee for the International Day of Light, Professor David Hutchinson, today announced that with Vector lighting up of the bridge, New Zealand would once again lead the world in the celebrations of a United Nations light event. “Three years ago New Zealand led the world in celebrating the International Year of Light, the initiative of New Zealander Professor John Dudley, who worked for many years to secure an International Year of Light to raise awareness of the achievements of light science and its applications. This time, the UN is celebrating the first official International Day of light, and once again, New Zealand leads the celebrations.”

Chatham Islanders could be forgiven for believing they are living largely alone, in the most easterly part of New Zealand, more than 800km from the South Island. But some visitors will be arriving there next week — a high-powered team of science outreach educators from the Otago Museum and University of Otago.
The "mini-expedition" will include museum director, physicist and astronomer Dr Ian Griffin, Dodd-Walls Centre for Photonics and Quantum Technologies director Prof David Hutchinson and museum science presentation co-ordinator Amadeo Enriquez-Ballestero. They will fly to the remote islands from Wellington on Monday and return late next week.
Prof Hutchinson and Mr Enriquez-Ballestero said they were excited about undertaking the "Extreme Science" project trip, backed by the Ministry of Business, Innovation and Employment’s Unlocking Curious Minds funding. They aimed to inspire young school pupils on the Chathams with what science and technology could already tell them about their world, and potential employment prospects. Museum science engagement director Dr Craig Grant said he also hoped the wider Chathams community "might see how new technologies can help offset some of the challenges of their remoteness, and enable them to take advantage of their unique location", such as linking the science of astronomy with night sky watching and "astrophotography" tourism.
Prof Hutchinson, of Otago University, stressed the expedition aimed "to build a relationship", and the funding included support for one of the teachers on the Chathams "to visit us back here at the university".
A telescope and seismometer would be taken to the Chathams and left behind with other science equipment. The legacy was important, he said. The team viewed this "as the start of a long relationship, not a one-off visit that is then forgotten".

View the DWC Interface Challenge video.
The Dodd-Walls Centre and the MacDiarmid Institute connected their top scientists with some of New Zealand’s most innovative companies to showcase what they could do for them. The Interface Industry Challenge was launched late last year asking companies to come up with commercial problems they couldn't solve within their own technological capability, which the Centres of Research Excellence (CoREs) would help solve for free.
The CoREs are virtual institutions that draw on the talent of top scientists from anywhere in the country in a particular research area. The Dodd-Walls Centre specialises in photonic and quantum technologies while the MacDiarmid Institute focuses on materials science and nanotechnology. Having signed non-disclosure agreements, the two CoREs are working on proofs of concept to solve problems for seven companies they’ve matched to various scientists. The scientists are now starting to produce some solutions the companies can use as a competitive advantage, and in some cases may even lead to new intellectual property.
The directors of both institutes, Professor David Hutchinson from the DWC and MacDiarmid’s Professor Thomas Nann say New Zealand industry needs to keep innovating to stay ahead. The challenge was a fun way of letting companies know what scientific help they could tap into, and both CoREs hope funding the initial research now will benefit them with longer-term research partnerships. The seven companies involved range from larger companies such as Fisher & Paykel Healthcare and Buckley Systems to start-ups Avertana, Lanaco, Aquafortus Technologies and Invisi Shield.
Andy West, a director on the boards of Aquafortus and Lanaco, says it is unusual to get free research from CoREs and that’s helpful for both companies he's helping govern which are still at the stage of “burning capital and are yet to enter full revenue profitability,” although Lanaco is close. Lanaco is a materials science company that uses fine wood blended with synthetic fibres to produce what it dubs as the world's most breathable air filter, while Aquafortus Technologies is developing water extraction technology involving organic chemistry which could potentially extract water from liquid waste materials and help desalination. “We have access to some extremely clever people across a range of universities as CoREs are not normally in just one site – they draw the best people from around the country in any given field. And we have access to really expensive scientific equipment we couldn’t afford ourselves,“ Dr West says.

Extreme hydrothermal conditions at an active plate-bounding fault; DWC Investigator, Professor Neil Broderick, is among a group of scientists who have recently had their paper published in "Nature".
Extremely high temperatures and fluid pressures have been measured in a borehole in the Alpine Fault in New Zealand, a Nature paper reports. The fault is expected to rupture in a magnitude-8 earthquake in the next few decades and the study could have broad implications for understanding earthquakes and fault zone geology.
The Alpine Fault is a major plate boundary fault that runs most of the length of New Zealand’s South Island. The fault produces large earthquakes approximately every 300 years, and it last ruptured in 1717. Rupert Sutherland and colleagues drilled a scientific borehole into the fault to examine the hydrothermal conditions therein.
They collected comprehensive rock, mud and seismological observations and found that temperatures and fluid pressures in the borehole were much higher than expected, particularly in the ‘hanging wall’ above the fault, where the average temperature gradient reached around 125 degrees Celsius per kilometre of depth. Values above 80 degrees Celsius per kilometre tend to be associated with volcanic regions, but there is no evidence for volcanism near this site. The authors conclude that these extreme hydrothermal conditions result from rapid fault movement, which transports rock and heat from greater depths, and fluid movement through fractured rocks, which concentrates heat into valleys.

DWC Investigator Dr Maarten Hoogerland was a contributing author of the following article recently published in Optica.
Large-scale quantum networks could allow a wide variety of applications in quantum computing and simulation. We have demonstrated the operation of a single node for use in such a network. A fiber ring cavity contains a nanofiber section, which mediates atom–light interactions through the evanescent field. We observe collective enhancement of the coupling rate between the ensemble of atoms and the light in the fiber.
This work, published in “Optica”, represents an important step toward implementing such a large-scale all-fiber quantum network.

The equipment Dr Mikkel Andersen and fellow researchers have developed to control individual atoms looks like the stuff of historic science fiction. There are seven lasers and a host of other scientific apparatus in a large machine, and when one researcher let a wire fall in front of a powerful laser it promptly began to smoke in a slightly alarming manner. But the equipment in a lab in a University of Otago science block has helped Dr Andersen and his team do what has not been done before; control individual atoms, making them appear wherever they want them to.

New gas sensing using photonic technology
13 February 2017
Dunedin-based Photonic Innovations has acquired complementary gas detection technology that makes workplaces such as meat processing companies and cool stores safer. The technology was acquired from Auckland company Southern Photonics. Both companies use lasers for detecting gases instead of chemical sensors, which were part of the safety problem at Pike River mine. Photonic Innovation chief executive Dr Ojas Mahapatra said lasers are more reliable and cheaper to operate.
