Abstract

The superfluidity and Bose–Einstein condensation of indirect excitons in coupled quantum dots or trapped atoms with induced dipole momenta (or dipole molecules) are studied by path-integral Monte Carlo simulations. The temperature dependencies of superfluid and Bose-condensed fraction are calculated at different strengths of interaction. Using Kosterlitz–Thouless recursion relations, we also predict the critical temperature in a macroscopic system of indirect excitons.
