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…
Persistent current oscillations in a double-ring quantum gas
T. Bland, I. V. Yatsuta, M. Edwards +4
Vorticity in closed quantum fluid circuits is known to arise in the form of persistent currents. In this work, we develop a method to engineer transport of the quantized vorticity…
Symmetry breaking in interacting ring-shaped superflows of Bose-Einstein condensates
Artem Oliinyk, Igor Yatsuta, Boris Malomed +1
We demonstrate that the evolution of superflows in interacting persistent currents of ultracold gases is strongly affected by symmetry breaking of the quantum vortex dynamics. We s…
Nonlinear dynamics of Josephson vortices in merging superfluid rings
Artem Oliinyk, Boris Malomed, Alexander Yakimenko
We consider merger of two parallel toroidal atomic Bose-Einstein condensates with different vorticities in a three-dimensional (3D) trap. In the tunnel-coupling regime, Josephson v…
Tunneling of persistent currents in coupled ring-shaped Bose-Einstein condensates
Artem Oliinyk, Alexander Yakimenko, Boris Malomed
Considerable progress in experimental studies of atomic gases in a toroidal geometry has opened up novel prospects for the investigation of fundamental properties of superfluid sta…
Analogues of Josephson junctions and black hole event horizons in atomic Bose-Einstein condensates
A. I. Yakimenko, O. I. Matsyshyn, A. O. Oliinyk +3
We study dynamical processes in coherently coupled atomic Bose-Einstein condensates. Josephson effects in ring-shaped and dumbbell geometries are theoretically investigated. Condit…
