Quench dynamics of an ultracold two-dimensional Bose gas
Paolo Comaron, Fabrizio Larcher, Franco Dalfovo +1
We study the dynamics of a two-dimensional Bose gas after an instantaneous quench of an initially ultracold thermal atomic gas across the Berezinskii-Kosterlitz-Thouless phase tran…

Collisionless sound in a uniform two-dimensional Bose gas
Miki Ota, Fabrizio Larcher, Franco Dalfovo +3
Using linear response theory within the Random Phase Approximation, we investigate the propagation of sound in a uniform two dimensional (2D) Bose gas in the collisionless regime.…
