摘要
We study the dynamics of two-component atomic Bose gases initially in a mixture encountering a sudden quench of the inter物種 interactions. The dynamics above the critical temperature T-c is studied using a leading-order large-N approximation that predicted a 相變 from mixing to phase separation as a function of the inter物種 coupling. Here, we explore the dynamics of this 相變 following a quench and compare our results to those found at zero temperature using the time-dependent Gross-Pitaevskii equations which ignore 量子 and thermal fluctuations. In the regime above T-c where no condensate is present, however, the time 演化 of the densities following the quench exhibits features similar to those found at zero temperature where only the condensates contribute to the densities. When the inter物種 intera
