Intraband Optical Transitions,confined electrons, but only to their center-of-mass motion. Indirect interaction of the FIR light with the relative motion of electrons, which would allow for the observation of the effects of electron-electron interactions in the FIR experiment, requires a coupling between the relative (rel) and the center-of-mass (cm) motions.作者: 油氈 時(shí)間: 2025-3-23 14:21

In the description of such a system, the effective-mass approximation can be applied if the perturbation potential varies slowly over the interatomic distance.
