虽然电子-电子相互作用不影响回旋共振根据科恩定理在一个完美的晶格的抛物半导体，它确实发挥了决定性的作用，在无序系统。本文给出了在强相互作用和磁场作用下无序体系中电偶极跃迁频率的一般表达式。这描述了以前的回旋共振实验在准二维系统中的磁量子极限，并预测一个低洼的无序诱导模式。
While the electron-electron interaction does not affect cyclotron resonance according to the Kohn theorem in a perfect lattice of a parabolic semiconductor, it does play a decisive role in disordered systems. We state a general expression for the frequencies of electric-dipole transitions in disordered systems in the presence of strong interactions and magnetic fields. This describes previous cyclotron-resonance experiments in quasi-two-dimensional systems in the magnetic quantum limit and predicts a low-lying disorder-induced mode.
