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…
Controlled acoustic-driven vortex transport in coupled superfluid rings
A. Chaika, A. O. Oliinyk, I. V. Yatsuta +4
Atomtronic quantum sensors based on trapped superfluids offer a promising platform for high-precision inertial measurements where the dynamics of quantized vortices can serve as se…
Acceleration-induced transport of quantum vortices in joined atomtronic circuits
A. Chaika, A. O. Oliinyk, I. V. Yatsuta +4
Persistent currents--inviscid quantized flow around an atomic circuit--are a crucial building block of atomtronic devices. We investigate how acceleration influences the transfer o…
