Magnetoexciton dispersion in GaAs-(Ga,Al)As single and coupled quantum
Z. G. Koinov
We discuss magnetoexcitons dispersion in single and coupled quantum wells using the Bethe-Salpeter (B-S) formalism. The B-S formalism in the case of quantum wells…

Cavity polaritons in the presence of symmetry-breaking disorder: closed-path time formalism
Z. Koinov
According to the mean-field theory of Zittartz, when subject to a symmetry-breaking disorder, the order parameter and the energy gap of an excitonic insulator are gradually suppres…
