ABSTRACT
We calculate the evaporative cooling dynamics of trapped one-dimensional Bose-Einstein condensates for parameters leading to a range of condensates and quasicondensates in the final equilibrium state, using the classical fields method. We confirm that solitons are created during the evaporation process by the Kibble-Zurek mechanism, but subsequently dissipate during thermalization. However, their signature remains in the phase coherence length, which is approximately conserved during dissipation in this system.
