"Synchronisation and entanglement in isolated quantum systems"


The understanding of dynamic collective phenomena has long been one of physics’ greatest challenges. The link between collective phenomena in the classical world and in the quantum world is still largely unknown. Synchronization – the link between the states of coupled measured values – is one of the basic collective dynamics phenomena in the classical systems of physics, chemistry, and biology. Entanglement, in contrast, is a purely quantum-mechanical phenomenon in many-body quantum systems. Hence synchronisation and entanglement both imply coordinated system states in multi-unit classical and quantum systems, respectively. Here, we present a direct link for a class of isolated quantum many-body systems, demonstrating that synchronisation emerges as an intrinsic system feature. Intriguingly, quantum coherence and entanglement arise persistently through the same transition as synchronisation. This direct link between classical and quantum cooperative phenomena makes us understand better strongly correlated quantum systems and can be readily observed in state-of-the-art experiments, for example, with ultracold atoms.
