Crossover in the dynamical critical exponent of a quenched two-dimensional Bose gas

Abstract
The authors investigate the phase ordering dynamics of a two-dimensional Bose gas following a quench, for varying dissipation strength. They characterize the dependence of the dynamical critical exponent, z, on the dissipation strength, finding an anomalous value of z in the dissipationless limit.
