R. I. Dzhioev,K. V. Kavokin,V. L. Korenev,M. V. Lazarev,B. Ya. Meltser,M. N. Stepanova,Boris P Zakharchenya,Daniel Gammon,D. S. Katzer +8 more
TL;DR: In this article, low-temperature electron-spin relaxation was studied by the optical orientation method in bulk n-GaAs with donor concentrations from 10.14 to 5.5
Journal ArticleDOI

TL;DR: This efficient electron spin relaxation mechanism in semiconductor InAs/GaAs quantum dots can be suppressed by an external magnetic field as small as 100 mT.
Journal ArticleDOI
Polariton-polariton interaction constants in microcavities
M. Vladimirova,Steeve Cronenberger,Denis Scalbert,K. V. Kavokin,Audrey Miard,Aristide Lemaître,Jacqueline Bloch,Dimitri Solnyshkov,Guillaume Malpuech,Alexey Kavokin +9 more
TL;DR: In this article, a microcavity in the strong coupling regime was used to estimate the strength of the interaction between polaritons with parallel or antiparallel spins, and the ratio was found to be strongly dependent on the detuning between exciton and photon modes.
Journal ArticleDOI
Anisotropic exchange interaction of localized conduction-band electrons in semiconductors
TL;DR: The spin-orbit interaction in semiconductors is shown to result in an anisotropic contribution into the exchange Hamiltonian of a pair of localized conduction-band electrons.
Journal ArticleDOI
Quantum Theory of Spin Dynamics of Exciton-Polaritons in Microcavities
TL;DR: It is shown that giant longitudinal-transverse splitting of the polaritons mixes their spin states, which results in beats between right- and left-circularly polarized photoluminescence of microcavities, as was recently experimentally observed.
