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…

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…
