Impurity Green's function of a one-dimensional Fermi-gas
O. Gamayun, A. G. Pronko, M. B. Zvonarev
We consider a one-dimensional gas of spin-1/2 fermions interacting through -function repulsive potential of an arbitrary strength. For the case of all fermions but one having sp…
The fate of a gray soliton in a quenched Bose-Einstein condensate
O. Gamayun, Yu. V. Bezvershenko, V. Cheianov
We investigate the destiny of a gray soliton in a repulsive one-dimensional Bose-Einstein condensate undergoing a sudden quench of the non-linearity parameter. The outcome of the q…
Reply to "Comment on 'Kinetic theory for a mobile impurity in a degenerate Tonks-Girardeau gas'"
O. Gamayun, O. Lychkovskiy, V. Cheianov
In our recent paper [Phys. Rev. E 90, 032132 (2014)] we have studied the dynamics of a mobile impurity particle weakly interacting with the Tonks-Girardeau gas and pulled by a smal…
Quantum Boltzmann equation for a mobile impurity in a degenerate Tonks-Girardeau gas
O. Gamayun
We investigate the large-time asymptotical behavior of a mobile impurity immersed in a degenerate Tonks-Girardeau gas. We derive a correct weak-coupling kinetic equation valid for…
Kinetic theory for a mobile impurity in a degenerate Tonks-Girardeau gas
O. Gamayun, O. Lychkovskiy, V. Cheianov
A kinetic theory describing the motion of an impurity particle in a degenerate Tonks-Girardeau gas is presented. The theory is based on the one-dimensional Boltzmann equation. An i…
