Relaxation dynamics of a mobile impurity injected into a one-dimensional Bose gas
Saptarshi Majumdar, Aleksandra Petković
The nonequilibrium dynamics of an impurity immersed with a finite velocity into a one-dimensional system of weakly interacting bosons is studied within the framework of the time-de…
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…
Mediated interaction between polarons in a one-dimensional Bose gas
Aleksandra Petkovic, Zoran Ristivojevic
We study a weakly-interacting one-dimensional Bose gas with two impurities coupled locally to the boson density. We derive analytical results for the induced interaction between th…
Density profile of a semi-infinite one-dimensional Bose gas and bound states of the impurity
Aleksandra Petkovic, Benjamin Reichert, Zoran Ristivojevic
We study the effect of the boundary on a system of weakly interacting bosons in one dimension. It strongly influences the boson density which is completely suppressed at the bounda…
Microscopic theory of the friction force exerted on a quantum impurity in one-dimensional quantum liquids
Aleksandra Petkovic
We study the motion of a slow quantum impurity in one-dimensional environments focusing on systems of strongly interacting bosons and weakly interacting fermions. While at zero tem…
