Angle-resolved spin noise spectroscopy in semiconductors: Two-state theory and experiments Open
Traditional spin noise spectroscopy generally does not address spatial spin correlations, which are in fact crucial for an in-depth understanding of spin relaxation. In semiconductors, one requires spin noise measurements at substantial an…

Exciton dynamics in CdTe/CdZnTe quantum well Open
Exciton energy structure and population dynamics in a wide CdTe/CdZnTe quantum well are studied by spectrally-resolved pump-probe spectroscopy. Multiple excitonic resonances in reflectance spectra are observed and identified by solving num…

Simultaneous measurements of nuclear-spin heat capacity, temperature, and relaxation in GaAs microstructures Open
Heat capacity of the nuclear spin system (NSS) in GaAs-based microstructures\nhas been shown to be much greater than expected from dipolar coupling between\nnuclei, thus limiting the efficiency of NSS cooling by adiabatic\ndemagnetization.…

Electron-induced nuclear magnetic ordering in -type semiconductors Open
Nuclear magnetism in n-doped semiconductors with positive hyperfine constant is revisited. Two kinds of nuclear magnetic ordering can be induced by resident electrons in a deeply cooled nuclear spin system. At positive nuclear spin tempera…

Complexity of the dipolar exciton Mott transition in GaN/(AlGa)N nanostructures Open
The Mott transition from a dipolar excitonic liquid to an electron-hole\nplasma is demonstrated in a wide GaN/(Al,Ga)N quantum well at $T=7$K by means\nof spatially-resolved magneto-photoluminescence spectroscopy. Increasing\noptical excit…

Spatiotemporal electronic spin fluctuations in random nuclear fields in n-CdTe Open
We report on the dynamics of electron spins in n-doped CdTe layers that differs significantly from the expected response derived from the studies dedicated to electron spin relaxation in n-GaAs. At zero magnetic field, the electron spin no…

Nuclear spin relaxation in-GaAs: From insulating to metallic regime Open
Nuclear spin relaxation is studied in n-GaAs thick layers and microcavity\nsamples with different electron densities. We reveal that both in metallic\nsamples where electrons are free and mobile, and in insulating samples, where\nelectrons…

Influence of magnetic quantum confined Stark effect on the spin lifetime of indirect excitons Open
We report on the unusual and counter-intuitive behaviour of spin lifetime of excitons in coupled semiconductor quantum wells (CQWs) in the presence of in-plane magnetic field. Instead of conventional acceleration of spin relaxation due to …

Single-shot measurement of transient nuclear magnetization with spin-noise spectroscopy in n-GaAs microcavities Open
We exploit spin noise spectroscopy (SNS) to directly observe build-up of dynamic nuclear polarization and relaxation of a perturbed nuclear spin-system to its equilibrium state in a single-shot experiment. The SNS experiments were performe…
