We show how to compute the eigenvalues of an anisotropic Schrodinger equation for light- and heavy-hole excitons in the presence of a magnetic field using a perturbational approach and a simplified deltalike interaction potential. Performing the calculation with a potential appropriate to bulk GaAs crystal we obtain a simple relation between the binding energy at zero field and the diamagnetic shift at low fields.

Abstract
We show how to compute the eigenvalues of an anisotropic Schrodinger equation for light- and heavy-hole excitons in the presence of a magnetic field using a perturbational approach and a simplified deltalike interaction potential. Performing the calculation with a potential appropriate to bulk GaAs crystal we obtain a simple relation between the binding energy at zero field and the diamagnetic shift at low fields.File in questo prodotto:
