Optical cooling of nuclear spins in GaAs/(Al,Ga)As quantum wells at subkelvin temperatures: Evidence of the dynamic self-polarization of nuclear spins
M. Kotur, D. Kudlacik, N. E. Kopteva +4
We investigate the dynamic polarization of nuclear spins in a nominally undoped GaAs/AlGaAs quantum well using two complementary experimental approaches: time-res…
Antiferromagnetic nonreciprocity of light emission in CuBO
A. R. Nurmukhametov, D. R. Yakovlev, V. Yu. Ivanov +4
Nonreciprocity of light emission, when the radiation intensity differs for two opposite propagation directions, is a rare phenomenon in solids because it requires a violation of th…
Coherence of dipole-forbidden Rydberg excitons in CuO measured by polarization- and time-resolved multi-photon spectroscopy
A. Farenbruch, N. V. Siverin, G. Uca +3
Quantum applications of solid state systems base upon generation and control of coherent electronic excitations. Prominent examples are exciton states in semiconductors excitable b…
Nonreciprocal magnetic-field-induced second harmonic generation of exciton polaritons in ZnSe
J. Mund, D. R. Yakovlev, A. Farenbruch +5
We report on the optical second harmonic generation (SHG) on the 1S exciton-polariton resonance in bulk ZnSe that is subject to an external magnetic field applied perpendicular to…
The effect of doping layers position on the heterojunction sharpness in (In,Al)As/AlAs quantum dots
T. S. Shamirzaev, D. R. Yakovlev, M. Bayer
Effect of doped layer placed in structures with indirect band-gap (In,Al)As/AlAs quantum dots (QDs) on heterointerface sharpness is investigated. We demonstrate that growth of n (p…
