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…
Quantum beats of exciton-polarons in CsPbI3 perovskite nanocrystals
A. V. Trifonov, M. O. Nestoklon, M. -A. Hollberg +10
Exciton-phonon interactions govern the energy level spectrum and thus the optical response in semiconductors. In this respect, lead-halide perovskite nanocrystals represent a uniqu…
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…
Dynamic polarization of nuclear spins by optically-oriented electrons and holes in lead halide perovskite semiconductors
Mladen Kotur, Pavel S. Bazhin, Kirill V. Kavokin +4
A theory of dynamic polarization of the nuclear spin system via optically-oriented charge carriers in lead halide perovskites is developed and compared with the experiments perform…
Magnetic field induced exciton spin dynamics in indirect band gap (In,Al)As/AlAs quantum dots
T. S. Shamirzaev, D. R. Yakovlev, D. S. Smirnov +5
The exciton recombination and spin dynamics are investigated both experimentally and theoretically in an ensemble of indirect band gap (In,Al)As/AlAs quantum dots (QDs) with type-I…
Confined acoustic phonons in CsPbI3 nanocrystals explored by resonant Raman scattering on excitons
Carolin Harkort, Ina V. Kalitukha, Nataliia E. Kopteva +8
Optical properties of the lead halide perovskites nanocrystals are controlled by confined excitons and rich spectrum of confined acoustic and optical phonons. We study experimental…
