We present a theoretical study of the exchange interaction in a system of spatially disordered magnetic moments. A typical example of such a system is an impurity semiconductor, whose magnetic properties are associated with the exchange interaction o

Electromagnetic waves in anisotropic media (e.g., weakly absorbing biaxial dielectric crystals) have a singular profile of the form $\propto (\mathbf{n} \mathbf{r}) \exp(i q \mathbf{n} \mathbf{r})$ along special directions, they are also known as Voi

The optical orientation of Mn$^{2+}$ spins in the first excited state $^4$T$_1$ was experimentally observed in bulk (Zn, Mn)Se ($x_\mathrm{Mn}=0.01$) in the an external magnetic field of up to $6\,$T in Faraday geometry. This occurred during quasi-re

We demonstrate the possibility of the optical orientation of excitons in the near field of the metal grating that covers a semiconductor nanostructure. Excitons generated this way have the wave vector greater than the wave vector of the incident radi

We study the dissipative phase transition in a quantum oscillator with two-photon drive and two-photon dissipation. Using the semi-classical Langevin equation and the Fokker-Plank approach, we construct a theory of non-perturbative quantum fluctuatio

We study the theoretical model of a ferromagnetic semiconductor as a system of randomly distributed Ising spins with a long-range exchange interaction. Using the density-of-states approach, we analytically obtain the magnetic susceptibility and heat
