Optical spin orientation of localized electrons and holes interacting with nuclei in an FACsPbIBr perovskite crystal
Dennis Kudlacik, Nataliia E. Kopteva, Mladen Kotur +8
Optical orientation of carrier spins by circularly polarized light is the basic concept and tool of spin physics in semiconductors. We study the optical orientation of electrons an…
Hole spin coherence in InAs/InAlGaAs self-assembled quantum dots emitting at telecom wavelengths
E. Evers, N. E. Kopteva, V. Nedelea +6
We report measurements of the longitudinal and transverse spin relaxation times of holes in an ensemble of self-assembled InAs/InAlGaAs quantum dots (QDs), emitting in the telecom…
Tuning the nuclei-induced spin relaxation of localized electrons by the quantum Zeno and anti-Zeno effects
V. Nedelea, N. V. Leppenen, E. Evers +3
Quantum measurement back action is fundamentally unavoidable when manipulating electron spins. Here we demonstrate that this back action can be efficiently exploited to tune the sp…
Resonant spin amplification in Faraday geometry
P. Schering, E. Evers, V. Nedelea +6
We demonstrate the realization of the resonant spin amplification (RSA) effect in Faraday geometry where a magnetic field is applied parallel to the optically induced spin polariza…
Shielding of external magnetic field by dynamic nuclear polarization in (In,Ga)As quantum dots
E. Evers, N. E. Kopteva, I. A. Yugova +3
The dynamics of the coupled electron-nuclear spin system is studied in an ensemble of singly-charged (In,Ga)As/GaAs quantum dots (QDs) using periodic optical excitation at 1 GHz re…
Suppression of nuclear spin fluctuations in an InGaAs quantum dot ensemble by GHz-pulsed optical excitation
E. Evers, N. E. Kopteva, I. A. Yugova +5
The coherent electron spin dynamics of an ensemble of singly charged (In,Ga)As/GaAs quantum dots in a transverse magnetic field is driven by periodic optical excitation at 1 GHz re…
