High frequency electric field induced nonlinear effects in graphene
Optical spin hall effect.
A remarkable analogy is established between the well-known spin Hall effect and the polarization dependence of Rayleigh scattering of light in microcavities and spin polarizations of the polaritons scattered clockwise and anticlockwise have different signs.
Exciton Diffusion and Halo Effects in Monolayer Semiconductors.
At elevated excitation densities, the initial Gaussian distribution of the excitons evolves into long-lived halo shapes with μm-scale diameter, indicating additional memory effects in the exciton dynamics.

In recent years, the physics community has experienced a revival of interest in spin effects in solid state systems. On one hand, solid state systems, particularly semicon- ductors and semiconductor…
Exciton fine structure and spin decoherence in monolayers of transition metal dichalcogenides
We study the neutral exciton energy spectrum fine structure and its spin dephasing in transition metal dichalcogenides such as MoS$_2$. The interaction of the mechanical exciton with its macroscopic…
Pump-probe Faraday rotation and ellipticity in an ensemble of singly charged quantum dots
A description of spin Faraday rotation, Kerr rotation and ellipticity signals for single- and multilayer ensembles of singly charged quantum dots (QDs) is developed. The microscopic theory considers…
Effect of electron-electron interaction on spin relaxation of charge carriers in semiconductors
An analysis of spin dynamics is presented for semiconductor systems without inversion symmetry that exhibit spin splitting. It is shown that electron-electron interaction reduces the rate of the…
Observation of the optical spin Hall effect
The spin Hall effect consists of the generation of a spin current perpendicular to the charge current flow. Thirty-five years after its prediction by Dyakonov and Perel'1, it is the focus of…

Second harmonic generation in graphene has been theoretically studied. Phenomenological analysis based on symmetry arguments is carried out. It is demonstrated that second harmonic generation in…
Resonant spin amplification in nanostructures with anisotropic spin relaxation and spread of the electronic g factor
Spin dynamics of electrons in semiconductors and structures with quantum wells under conditions where pumping and probing are performed in the form of a periodical series of pulses is theoretically…
