Sažetak
We present our recent study [1] of thermal properties of a trapped Bose-Bose mixture in a dilute regime using quantum Monte Carlo methods. We have investigated the dependence of the superfluid density and the condensate fraction on temperature, for the mixed and separated phases. To this end, we have used the path-integral Monte Carlo method for finite temperatures and the diffusion Monte Carlo method, in the zero-temperature limit, comparing the obtained results with solutions of the coupled Gross-Pitaevskii equations. We notice anisotropy of superfluid density in some phase-separated mixtures. Our results also show that the superfluid density and condensate fraction have slightly different temperature evolution, showing noteworthy situations where the superfluid fraction is smaller than the condensate fraction.
