Non-Markovian hole spin kinetics in -type GaAs quantum wells
arXiv:0708.4086 · doi:10.1103/PhysRevB.76.193312
Abstract
Based on fully microscopic kinetic spin Bloch equation approach, we show the non-Markovian effect in spin dephasing of heavy holes in -type GaAs quantum wells. The non-Markovian effect manifests itself in spin dephasing when the mean spin precession time is shorter than the momentum relaxation time. The spin dephasing becomes slower when the non-Markovian effect is important. Moreover, quantum spin beats due to the memory effect of the non-Markovian hole-longitudinal optical phonon scattering are predicted.
