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…
Acoustic analogue of Hawking radiation in quantized circular superflows of Bose-Einstein condensates
Igor Yatsuta, Boris Malomed, Alexander Yakimenko
We propose emulation of Hawking radiation (HR) by means of acoustic excitations propagating on top of persistent current in an atomic Bose-Einstein condensate (BEC) loaded in an an…
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…
