Abstract
Motivated by experiments in bosonic mixtures composed of a single element in two different hyperfine states, we study bosonic binary mixtures in the presence of Josephson interactions between species. We focus on a particular model with O(2) isospin symmetry, lifted by an imbalanced population parametrized by a Rabi frequency, ΩR, and a detuning, ν, which couples the phases of both species. We have studied the model at mean-field approximation plus Gaussian fluctuations. We have found that both species simultaneously condensate below a critical temperature Tc and the relative phases are locked by the applied laser phase, α. Moreover, the condensate fractions are strongly dependent on the ratio ΩR/â£Î½â£ that is not affected by thermal fluctuations.
