The density of a one-dimensional Bose gas far from an impurity
Aleksandra Petkovic, Zoran Ristivojevic
We consider an impurity in a one-dimensional weakly-interacting Bose gas and analytically calculate the density profile of the Bose gas. Within the mean-field approximation, by inc…

Dissipative dynamics of a heavy impurity in a Bose gas in the strong coupling regime
Aleksandra Petković, Zoran Ristivojevic
We study the motion of a heavy impurity in a one-dimensional Bose gas. The impurity experiences the friction force due to scattering off thermally excited quasiparticles. We presen…
