For a semiconductor with single isotropic conduction and valence bands, the effective
biexciton-biexciton interaction is derived starting from the second-quantization …

Recently theoretical physicists have paid considerable interest to open systems in contact
with different kinds of reservoires or coherent driving forces [1, 2]. These open systems may …

The dependence of the binding energy W of the biexciton on the electronhole mass ratio σ is
discussed. The bounds from above and from below on the possible curves y= W (σ) have …

A report on the theoretical and experimental works in biexcitons studies in semconductors is
given. Energies spectra of biexcitons, the conditions of their formation as well as non linear …

The influence of excitonic localization on the binding energy of biexcitons is investigated for
quasi-three-dimensional and quasi-two-dimensional Al x Ga 1− x As structures. An increase …

A microscopic theory is developed concerning the coherent pairing of Wannier-Mott type
excitons in insulators and semiconductors. The coherent pairing of excitons occurs in the …

A new method is described that allows to detect the presence of a Bose condensate of
biexcitons in a direct band gap material. It probes the accumulation of biexcitons in the …

Starting from a previously derived many‐particle equation describing biexciton states,
dynamical screening effects in the irreducible exciton‐exciton interaction are taken into …

The calculation of the ground state energy of a biexciton is quite involved, and that of the
excited states even more so. Karp and Moskalenko [1](KM) proposed a model, which is …

Biexciton ground state energy has been calculated using several trial functions which
possess proper symmetry, allow analytical evaluation of the energy matrix elements and …
