We study the dynamics of two-component atomic Bose gases initially in a mixture encountering a sudden quench of the inter-species interactions. The dynamics at zero-temperature is studied by time-dependent Gross-Pitaevskii equations while that at high temperature (above the critical temperature) is studied by a leading-order large-N approximation. When the inter-species interaction jumps above the critical value, we observe dynamical transitions from a homogeneous mixture to a phase-separated structure for both cases. Our simulations suggest that even at high temperature this dynamical transition should still be observable in experiments.
