Optical Cooling of Nuclear Spins in a CdTe/CdZnTe Quantum Well: The Impact of Kinetic Local Fields on Cooling Efficiency
V. M. Litvyak, P. S. Bazhin, R. André +1
The efficiency of optical cooling of nuclear spins in a CdTe/CdZnTe quantum well is investigated as a function of an external magnetic field. Our results confirm that there is inde…
Nuclear spin-spin interactions in CdTe probed by zero and ultra-low-field optically detected NMR
V. M. Litvyak, P. Bazhin, R. André +2
Nuclear magnetic resonance (NMR) is particularly relevant for studies of internuclear spin coupling at zero and ultra-low fields (ZULF), where spin-spin interactions dominate over…
Nuclear spin relaxation mediated by donor-bound and free electrons in wide CdTe quantum wells
Boris F. Gribakin, Valentina M. Litvyak, Mladen Kotur +4
The nuclear spin systems in CdTe/(Cd,Zn)Te and CdTe/(Cd,Mg)Te quantum wells (QW) are studied using a multistage technique combining optical pumping and Hanle effect-based detection…
Local field of spin-spin interactions in the nuclear spin system of n-GaAs
V. M. Litvyak, R. V. Cherbunin, V. K. Kalevich +1
At low lattice temperatures the nuclear spins in a solid form a closed thermodynamic system that is well isolated from the lattice. Thermodynamic properties of the nuclear spin sys…
Stochastic circular persistent currents of exciton polaritons
J. Borat, Roman Cherbunin, Evgeny Sedov +8
We keep track of the orbital degree of freedom of an exciton polariton condensate, confined in an optical trap, and reveal the stochastic switching of persistent annular polariton…
Simultaneous measurements of nuclear spin heat capacity, temperature and relaxation in GaAs microstructures
M. Vladimirova, S. Cronenberger, A. Colombier +4
Heat capacity of the nuclear spin system (NSS) in GaAs-based microstructures has been shown to be much greater than expected from dipolar coupling between nuclei, thus limiting the…
Warm-up spectroscopy of quadrupole-split nuclear spins in n-GaAs epitaxial layers
V. M. Litvyak, R. V. Cherbunin, V. K. Kalevich +4
The efficiency of the adiabatic demagnetization of nuclear spin system (NSS) of a solid is limited, if quadrupole effects are present. Nevertheless, despite a considerable quadrupo…
Deep optical cooling of coupled nuclear spin-spin and quadrupole reservoirs in a GaAs/(Al,Ga)As quantum well
M. Kotur, D. O. Tolmachev, V. M. Litvyak +4
The selective cooling of As spins by optical pumping followed by adiabatic demagnetization in the rotating frame is realized in a nominally undoped GaAs/(Al,Ga)As quantum we…
