"Coherently-Coupled Potassium BECs: Interaction Control and Density-Dependent Gauge Fields"
In potassium-39 the interactions between different spin states are highly tuneable due to a variety of Feshbach resonances. Through coherent coupling between two spin states of a Bose-Einstein condensate where the intra- and interspecies scattering lengths are all different, we demonstrate fast interaction control, which we use to perform interaction quenches leading to modulational instability. Furthermore, we demonstrate a density dependent gauge field by introducing further coupling between the spin and momentum of the atoms using optical Raman transitions.
