Abstract
We report the results of self-consistent density-functional electronic-structure calculations for parabolic-profile GaAs-Al x Ga 1-x As quantum wells in a magnetic field within the effective-mass approximation. We discuss in general the treatment of inhomogeneous effective mass in self-consistent electronic-structure calculations and, in particular, include the parabolic-well effective-mass variation across the well. We consider both in-plane and transverse-magnetic field. In the former case, the magnetic field couples the in-plane and transverse degrees of freedom
