Zusammenfassung

We present an approach to spin dynamics by extending the optical Bloch equation s for the driven two-level system to derive microscopic expressions for the tra nsverse and longitudinal spin relaxation times. This is done for the 6-level sy stem of electron and hole subband states in a semiconductor or a semiconductor quantum structure to account for the degrees-of-freedom of the carrier spin and ...
