Real-space collapse of a polariton condensate
L. Dominici, M. Petrov, M. Matuszewski +10
Polaritons in microcavities are versatile quasi-2D bosonic particles with a high degree of coherence and strong nonlinearities, thanks to their hybrid light-matter character. In th…

Perpetual motion of a mobile impurity in a one-dimensional quantum gas
Oleg Lychkovskiy
Consider an impurity particle injected in a degenerate one-dimensional gas of noninteracting fermions (or, equivalently, Tonks-Girardeau bosons) with some initial momentum . W…

Momentum relaxation of a mobile impurity in a one-dimensional quantum gas
E. Burovski, V. Cheianov, O. Gamayun +1
We investigate the time evolution of the momentum of an impurity atom injected into a degenerate Tonks-Girardeau gas. We establish that given an initial momentum the impurity…
