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…
Single-beam resonant spin amplification of electrons interacting with nuclei in a GaAs/(Al,Ga)As quantum well
M. Kotur, F. Saeed, R. W. Mocek +6
The dynamic polarization of nuclear spins interacting with resident electrons under resonant excitation of trions is studied in a nominally undoped GaAs/(Al,Ga)As quantum well. Unl…
Nuclear spin-lattice relaxation in p-type GaAs
M. Kotur, R. I. Dzhioev, M. Vladimirova +6
Spin-lattice relaxation of the nuclear spin system in p-type GaAs is studied using a three-stage experimental protocol including optical pumping and measuring the difference of the…
High-efficiency optical pumping of nuclear polarization in a GaAs quantum well
R. W. Mocek, V. L. Korenev, M. Bayer +6
The dynamic polarization of nuclear spins by photoexcited electrons is studied in a high quality GaAs/AlGaAs quantum well. We find a surprisingly high efficiency of the spin transf…
