Abstract
The single-particle spectrum of holes in parabolic quantum dots in a magnetic field is investigated. The calculted Landau-level structure and allowed transition-energy spectrum for the heavy and light holes is considerably more complicated than that obtained for quantum dots containing electrons. This is because of the valence-band mixing, which produces strong anticrossings of the Landau levels and substantial wave-function mixing. It is noted that the band mixing causes Kohn’s theorem to be violated, thus allowing for a richer far-infrared optical response.
