摘要：

The effects of electron-electron interactions on two-component cyclotron resonance are studied numerically in a two-dimensional system. The resonance can be considered roughly as consisting of two peaks if a broadening introduced phenomenologically is sufficiently large. At low temperatures the two peaks repel each other and their intensities are modified strongly, while they merge into a single peak at high temperatures. The results qualitatively explain recent experiments on spin-split cyclotron resonance in GaAs/AlGaAs heterostructures.
