Dynamical galactic effects induced by stable vortex structure in bosonic dark matter
K. Korshynska, Y. M. Bidasyuk, E. V. Gorbar +2
The nature of dark matter (DM) remains one of the unsolved mysteries of modern physics. An intriguing possibility is to assume that DM consists of ultralight bosonic particles in t…
Phonon-Josephson resonances in atomtronic circuits
Y. M. Bidasyuk, O. O. Prikhodko, M. Weyrauch
We study the resonant excitation of sound modes from Josephson oscillations in Bose-Einstein condensates. From the simulations for various setups using the Gross-Pitaevskii mean-fi…
Generation and decay of persistent current in a toroidal Bose-Einstein condensate
A. I. Yakimenko, S. I. Vilchinskii, Y. M. Bidasyuk +3
Persistent current, or "flow without friction", as well as quantum vortices are the hallmarks of superfluidity. Recently a very long-lived persistent flow of atoms has been experim…
Vortices in a toroidal Bose-Einstein condensate with a rotating weak link
A. I. Yakimenko, Y. M. Bidasyuk, M. Weyrauch +2
Motivated by a recent experiment [K.C. Wright et. al. Phys. Rev. Lett. 110, 025302 (2013)], we investigate deterministic discontinuous jumps between quantized circulation states in…
JM-ECS: A hybrid method combining the -matrix and ECS methods for scattering calculations
Y. Bidasyuk, W. Vanroose, J. Broeckhove +2
The paper proposes a hybrid method for calculating scattering processes that combines the -matrix method with exterior complex scaling as an absorbing boundary condition. It rep…
