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…
Collective dynamics of active matter with orientation-weighted alignment
Bohdan Dobosh, Alexander Yakimenko
We study an agent-based model of self-propelled particles with a velocity-dependent alignment rule. This interaction is orientation weighted and acts along the line connecting neig…
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…
Collective Excitations of Self-Gravitating Ultralight Dark Matter Cores
Luca Salasnich, Alexander Yakimenko
A distinctive feature of ultralight bosonic dark matter is its ability to form a Bose-Einstein condensate with a dense, stationary configuration at the center of galactic halos. In…
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…
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…

K. Korshynska, O. O. Prykhodko, E. V. Gorbar +2
Theoretical analysis of the interaction between superfluid dark matter and rotating supermassive black holes offers a promising framework for probing quantum effects in ultralight…
Solitons in Quasiperiodic Lattices with Fractional Diffraction
Eduard Pavlyshynets, Luca Salasnich, Boris A. Malomed +1
We study the dynamics of solitons under the action of one-dimensional quasiperiodic lattice potentials, fractional diffraction, and nonlinearity. The formation and stability of the…
