Laikhtman and R. Rapaport<br/>In this paper we present a study of an exciton system where electrons and holes are confined in double quantum well structures. The dominating interaction between excitons in such systems is a dipole-dipole repulsion. We show that the tail of this interaction leads to a strong correlation between ex...<br/>[Phys. Rev.
