Mean-field theory of the electromagnon resonance
Pavel A. Andreev, Mariya Iv. Trukhanova
We present the analytical theory of the electromagnon resonance for the multiferroics of spin origin. We consider the spin density evolution under the influence of magnetoelectric…

Regimes of optical transparency and instabilities of collinear dielectric ferromagnetic materials in the presence of the dynamic magnetoelectric effect
Pavel A. Andreev
The contribution of the polarization associated with the noncollinear parts of spins in the dielectric permeability tensor of multiferroic materials is considered. As the equilibri…

Two-fluid hydrodynamics of cold atomic bosons under influence of the quantum fluctuations at non-zero temperatures
Pavel A. Andreev
Ultracold Bose atoms is the physical system, where the quantum and nonlinear phenomena play crucial role. Ultracold bosons are considered at the small finite temperatures. Bosons a…
