Abstract

The characteristic single-particle excitation energy of typical quantum dots lies in the far infrared (FIR) range. Depending on the dot dimensions, this energy varies between a fraction to tens of meV. As described previously, in Sect. 4.1, due to the fact that the wavelength of light from this range (≈ 1 mm) considerably exceeds the dot diameter (< 1µm), the FIR radiation cannot couple directly to the internal (relative) motion of the system of 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.
