Fine structure of the stripe phase in ring-shaped Bose-Einstein condensates with spin-orbital-angular-momentum coupling
Y. M. Bidasyuk, K. S. Kovtunenko, O. O. Prikhodko
We report on a theoretical study of a ring-shaped Bose-Einstein condensate with Raman-induced spin-orbital-angular-momentum coupling. We analyze the structure of the ground-state o…
Dispersion relations and self-localization of quasiparticles in coupled elongated Bose-Einstein condensates
M. R. Momme, O. O. Prikhodko, Y. M. Bidasyuk
We present a detailed study of the spectrum and dispersion of Bogoliubov quasiparticles in two coupled elongated Bose-Einstein condensates. We develop an analytically solvable mode…
Projected Gross-Pitaevskii equation for ring-shaped Bose-Einstein condensates
O. O. Prikhodko, Y. M. Bidasyuk
We propose an alternative implementation of the Projected Gross-Pitaevskki equation adapted for numerical modeling of the atomic Bose-Einstein condensate trapped in a toroidally-sh…
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…
