The dynamics above the critical temperature $T_c$ is studied using a leading order large-N approximation that predicted a phase transition from mixing to phase separation as a function of the inter-species coupling. Here we explore the dynamics of this phase transition following a quench and compare our results to those found at zero temperature using the time-dependent Gross-Pitaevskii equations which ignore quantum and thermal fluctuations.
