Josephson spectroscopy in a circular atomic tunnel junction with acceleration-induced symmetry breaking
Yurii Borysenko, Yuriy Bidasyuk, Olena Prykhodko +5
We study Josephson dynamics in a long atomic Bose-Josephson junction formed by two tunnel-coupled coplanar Bose-Einstein-condensate rings. An in-plane linear acceleration breaks th…
Dynamics of repeated BEC formation and extraction in dimple traps
Kyrylo Kovalchuk, Dominik Pfeiffer, Ludwig Lind +3
We investigate repeated Bose-Einstein-condensate (BEC) formation and extraction in a dimple trap embedded in a reservoir of thermal atoms using a kinetic model. The model includes…
Acceleration-driven dynamics of Josephson vortices in coplanar superfluid rings
Yurii Borysenko, Nataliia Bazhan, Olena Prykhodko +4
Precise control of topologically protected excitations, such as quantum vortices in atomtronic circuits, opens new possibilities for future quantum technologies. We theoretically i…
Trapping of Bose-Einstein condensates in a three-dimensional dark focus generated by conical refraction
D. Pfeiffer, L. Lind, J. Küber +5
We present an efficient three-dimensional dark-focus optical trapping potential for neutral atoms and Bose-Einstein condensates. This "optical bottle" is created by a single blue-d…
