Abstract
We extend our study of the far-infrared optical-absorption spectrum of electrons confined in an imperfect parabolic quantum well to the case of in-plane magnetic field, where the spectrum is in general continuous. Using periodic boundary conditions and the random-phase approximation, we obtain good agreement with experiment over a magnetic-field range of 5–14 T.
