Berezinskii–Kosterlitz–Thouless phase induced by dissipating quasisolitons
Abstract We theoretically study the sound propagation in a two-dimensional weakly interacting uniform Bose gas. Using the classical fields approximation we analyze in detail the properties of density waves generated both in a weak and strong perturbation regimes. While in the former case density exc...
