摘要：

We use the Bethe-Salpeter formalism to study the effects of the Frohlich electron-LO-ponon interaction on the dispersion of two-dimensional magnetoexcitons in polar crystals. The lowest Landau level approximation is applied to evaluate analytically both the binding energy and the exciton mass in a strong magnetic field regime. (c) 2009 WILEY-VCH Verlag GmbH & Co.
