✦ Synopsis

The superfluidity and Bose-Einstein condensation of indirect excitons in coupled quantum dots or trapped atoms with Ž . 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.

An exciton may be attached to a quantum dot if the conduction-band and valence-band offsets, for a given dot size, satisfy certain inequalities. Alternatively, for a set of finite offsets, the dot dimension must exceed a minimal size for an exciton to be bound to the dot. These critical offset or do
