Interacting Bose-Bose mixtures at finite temperature

We examine the role of thermal fluctuations in 2D uniform binary condensate mixtures of dilute atomic gases. In particular, we use the Stochastic Projected Gross-Pitaevskii formalism to probe the impact of non-condensate atoms to the phenomenon of phase-separation in two-component Bose-Einstein condensates. We demonstrate that, in comparison to zero temperature, there is a suppression in the phase-separation of the binary condensates at non-zero temperature. We also show that a mixed phase gives rise to a fully separated one at finite temperature. Finally, these phases are characterized by measuring the speed of sound at finite temperature.
