Efros<br/>A description of spin Faraday rotation, Kerr rotation and ellipticity signals for single- and multilayer ensembles of singly charged quantum dots (QDs) is developed. The microscopic theory considers both the single pump-pulse excitation and the effect of a train of such pulses, which in the case of ...<br/>[Phys. Rev. B 80, 104436] Published Tue Sep 29, 2009 I.

At temperatures below 50 K, strong modifications of the nonlocal spin signal are found that are characteristic for hyperfine coupling between conduction electrons and dynamically polarized nuclear spins.
