Description

As a test of the Kibble-Zurek mechanism (KZM) of defect formation, we simulate the Bose-Einstein condensation transition in a toroidally confined Bose gas by using the stochastic projected Gross-Pitaevskii equation, with and without the energy-damping reservoir interaction. Energy-damping alters the scaling of the winding-number distribution with the quench time-a departure from the universal KZM theory that relies on equilibrium critical exponents. Numerical values are obtained for the corre...
