Abstract
The hole magnetoplasmon dispersion of GaAs/AlxGa1-xAs heterostructures is calculated in a time-dependent Hartree-Fock approximation. We find that cyclotron-resonance positions are significantly shifted by hole-hole interactions and that the hole magnetoplasmon dispersion increases monotonically with wave vector. Both results differ from the case of an electron gas, where cyclotron-resonance-position shifts are forbidden by Kohns theorem, and are consequences of strong heavy- and light-hole mixing.
