Hydrodynamical approach to chirality production during axion inflation
E. V. Gorbar, A. I. Momot, O. O. Prikhodko +1
We study chirality production in the pseudoscalar inflation model of magnetogenesis taking into account the Schwinger effect and particle collisions in plasma in the relaxation tim…
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…
