Cooling and heating nuclear spins by strongly localized electrons
D. S. Smirnov, K. V. Kavokin
The concept of nuclear spin temperature has been a cornerstone of the theory of dynamic nuclear spin polarization by electrons in various semiconductor structures for decades. Stil…
Spin light emitting diode based on exciton fine structure tuning in quantum dots
A. V. Shumilin, T. S. Shamirzaev, D. S. Smirnov
We propose a concept of quantum dot based light emitting diode that produces circularly polarized light due to the tuning of the exciton fine structure by magnetic field and electr…
Kondo enhancement of current induced spin accumulation in a quantum dot
V. N. Mantsevich, D. S. Smirnov
Weak spin-orbit coupling produces very limited current induced spin accumulation in semiconductor nanostructures. We demonstrate a possibility to increase parametrically the spin p…
Optical orientation of excitons in a longitudinal magnetic field in indirect band gap (In,Al)As/AlAs quantum dots with type-I band alignment
T. S. Shamirzaev, A. V. Shumilin, D. S. Smirnov +5
The exciton recombination and spin dynamics in (In,Al)As/AlAs quantum dots (QDs) with indirect band gap and type-I band alignment are studied. The negligible (less than eV)…
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…
Spin noise in birefringent and inhomogeneous media
V. O. Kozlov, N. S. Kuznetsov, D. S. Smirnov +3
It is known that linear birefringence of the medium essentially hinders measuring the Faraday effect. For this reason, optically anisotropic materials have never been considered as…
Nuclear spin dynamics and noise in anisotropic large box model
A. V. Shumilin, D. S. Smirnov
We consider the central spin model in the box approximation taking into account external magnetic field and anisotropy of the hyperfine interaction. From the exact Hamiltonian diag…
Dynamic Valley Polarization in Moire Quantum Dots
D. S. Smirnov
We describe the effects of the crossing of the exciton levels in moire quantum dots in external magnetic field. We demonstrate that the unpolarized light can create significant dyn…
Theory of optically detected spin noise in nanosystems
D. S. Smirnov, V. N. Mantsevich, M. M. Glazov
Theory of spin noise in low dimensional systems and bulk semiconductors is reviewed. Spin noise is usually detected by optical means, continuously measuring the rotation angle of t…
Dynamic polarization of electron spins interacting with nuclei in semiconductor nanostructures
D. S. Smirnov, T. S. Shamirzaev, D. R. Yakovlev +1
We suggest a new spin orientation mechanism for localized electrons: . The angular momentum for the electr…
Nonlinear light absorption in colloidal CdSe/CdS nanoplatelets
V. N. Mantsevich, D. S. Smirnov, A. M. Smirnov +5
We investigated the nonlinear optical properties of CdSe/CdS nanoplatelets in the vicinity of heavy hole and light hole exciton resonances. The two color pump-probe technique was a…
Spin-noise-based magnetometry of an -doped GaAs microcavity in the field of elliptically polarized light
I. I. Ryzhov, G. G. Kozlov, D. S. Smirnov +8
Recently reported optical nuclear orientation in the -doped GaAs microcavity under pumping in nominal transparency region of the crystal [Appl. Phys. Lett. , 24240…
