The conditions of induced and spontaneous Kosterlitz–Thouless-type Bose–Einstein condensation (BEC) of excitons and biexcitons in a microcavity-embedded quantum well are discussed. As an example the Zn 1− x Cd x Se/ZnSe quantum well is consider

Transversal-longitudinal splittings of the components of the quadrupole-active exciton level characterized by irreducible representation Γ + 5 in Cu 2 O crystal were deduced. They arise due to long-range dipole-dipole interaction. The transition dip

The renormalization of the energetical spectrum of paraexcitons in the presence of a Bose-Einstein condensate (BEC) of orthoexcitons or at least of their saturation is studied. Due to the conversion of a pair of orthoexcitons into a pair of paraexcit

It is shown that in ZnSe/(Zn, Mn)Sequantum wells six biexcitonic states can exist. The group-theoretical classification of these states is performed. The probabilities of biexciton two-photon absorption, hyper-Raman scattering, and radiative recombin
