Abstract
It is shown that light absorption in a 2D Wigner crystal is possible not only with creation of magnetoexcitons with zero momentum but also with finite momentum in the reciprocal Wigner lattice. The magnitude of such an absorption is small due to Kohn’s theorem and is estimated using nonparabolic terms in the electron dispersion, and small terms describing the interaction with phonons and impurities. The same process was estimated for inelastic light scattering, where the effect is large.
