Collective excitations and tunneling dynamics in long bosonic Josephson junctions
M. R. Momme, Y. M. Bidasyuk, M. Weyrauch
We investigate the low-energy dynamics of two coupled anisotropic Bose-Einstein condensates forming a long Josephson junction. The theoretical study is performed in the framework o…
Finite-temperature dynamics of a bosonic Josephson junction
Y. M. Bidasyuk, M. Weyrauch, M. Momme +1
In the framework of the stochastic projected Gross-Pitaevskii equation we investigate finite-temperature dynamics of a bosonic Josephson junction (BJJ) formed by a Bose-Einstein co…
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…
Stable Hopf solitons in rotating Bose-Einstein condensates
Y. M. Bidasyuk, A. V. Chumachenko, O. O. Prikhodko +3
We reveal that Hopf solitons can be stabilized in rotating atomic Bose-Einstein condensate. The Hopfion is a matter-wave vortex complex which carries two independent winding number…
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…
