    Controlled switching between quantum states in the exciton–polariton condensate

    Optically controlled switching between modes of a polariton laser having different symmetries has been demonstrated experimentally. The microscopic shift of the optical excitation spot dramatically changes the...

    Nuclear Spin relaxation mediated by Fermi-edge electrons in n-type GaAs

    A method based on the optical orientation technique was developed to measure the nuclear-spin lattice relaxation time T 1 in semiconductors. It was applied to bulk n-type GaAs, where T ...

    Spin polarization dynamics and the Hanle effect for a strong exchange interaction in the exciton

    The exciton spin dynamics in a quantum well with a magnetic field applied in its plane is analyzed theoretically. The exchange interaction between the electron and the hole is assumed to be strong. The width o...

    The hanle effect in nonuniformly doped GaAs

    Spin density distribution in the GaAs/AlGaAs heterostructure was studied under steady-state optical orientation conditions. A comprehensive analysis of the dynamics and relaxation processes responsible for the...

    Luminescence polarization and spontaneous lowering of symmetry caused by magnetic-polaron formation in semimagnetic-semiconductor quantum wells

    An experimental and theoretical study of the magnetic polaron states of two-dimensional excitons in quantum wells based on semimagnetic semiconductors (Cd,Mn)Te is reported. It is shown that magnetic-polaron f...

    Determination of the sign of the conduction-electron g factor in semiconductor quantum wells by means of the Hanle effect and spin-quantum-beat techniques

    A method of measuring the sign of the conduction-electron g factor in semiconductor quantum-wells is proposed, based on determination of the sense of electron-spin Larmor precession by the Hanle effect or spin-qu...
