Abstract
Many-body effects may be conveniently studied in the two dimensional hole system (2DHS) formed in a GaAs/(Al,Ga)As heterostructure. This 2DHS exhibits extreme valence subband non-parabolicity and a large zero-field splitting of the dispersion relationships of the two spin projections1. In consequence, a complex cyclotron resonance (CR) spectrum might be expected2. However, the experimental study of CR in this Communication shows that such a complex spectrum is in fact absent in most cases. This absence is discussed in terms of a collective cyclotron motion due to Coulomb interactions between holes. Additional evidence for such a collective motion effect is provided by the observation of a very strong temperature dependence of the apparent CR position.
