Coherent phase slips in coupled matter-wave circuits

Quantum phase slips are a dual process of particle tunneling in coherent networks. Besides being central interest to condensed matter physics, quantum resources that sought be manipulated circuits. Here, we devise specific matter-wave circuit enlightening slips. Specifically, investigate the many-body dynamics two side-by-side ring-shaped neutral bosonic systems coupled through weak link. By imparting suitable magnetic flux, persistent currents flow each ring with given winding numbers. We demonstrate occur as number transfer among rings, populations remaining nearly constant. Such phenomenon occurs result entanglement circulating states, that, such, cannot captured by mean-field treatment system. Our work can relevant for observation cold-atom experiments and their manipulation To make contact field, show has clear signatures momentum distribution system providing time-of-flight image condensate.Received 20 December 2021Accepted 18 March 2022DOI:https://doi.org/10.1103/PhysRevResearch.4.L022038Published American Physical Society under terms Creative Commons Attribution 4.0 International license.
