Modeling spontaneous breaking of time-translation symmetry
Krzysztof Sacha
We show that an ultra-cold atomic cloud bouncing on an oscillating mirror can reveal spontaneous breaking of a discrete time translation symmetry. In many-body simulations we illus…

Proper phase imprinting method for a dark soliton excitation in a superfluid Fermi mixture
Krzysztof Sacha, Dominique Delande
It is common knowledge that a dark soliton can be excited in an ultra-cold atomic gas by means of the phase imprinting method. We show that, for a superfluid fermionic mixture, the…

Simulation of non-Abelian lattice gauge fields with a single component gas
Arkadiusz Kosior, Krzysztof Sacha
We show that non-Abelian lattice gauge fields can be simulated with a single component ultra-cold atomic gas in an optical lattice potential. An optical lattice can be viewed as a…
