Abstract
We present a microscopic theory of the effects of the electron-electron interaction on the effective mass and the anomalous Landé g factor in an inversion layer. We find that the inclusion of previously neglected many-body effects, associated with charge- and spin-fluctuation-induced vertex corrections, is crucial. The present approach is based on a new self-consistent determination of the many-body local fields. Our theory has no free parameters and the results are in good agreement with the established experimental findings.Keywords
