dc.description.abstract | Nonequilibrium dynamics of non-interacting bosons in a one-dimensional ring-shaped lattice is studied by
means of the kinetic Monte Carlo method. The system is approximated by the classical XY model (the kinetic
term is neglected) and then the simulations are performed for the planar classical spins. We study the dynamics
that follows a finite-time quench to zero temperature. If the quench is slow enough the system can equilibrate and
finally reaches the ground state with uniform spin alignment. However, we show that if the quench is faster than
the relaxation rate, the system can get locked in a current-carrying metastable state characterized by a nonzero
winding number. We analyze how the zero-temperature state depends on the quench rate. | pl_PL |
