Spin-current model of electric polarization with the tensor gyromagnetic ratio
Mariya Iv. Trukhanova, Pavel A. Andreev
The spin-current model of electric polarization of spin origin is developed for a magnetic structure with anisotropic tensor gyromagnetic ratio (g-factor). Three mechanisms of the…
Dynamic effects of external axion fields in a system of many particles with spin
Mariya Iv. Trukhanova, Yuri N. Obukhov
We develop the theoretical model that describes dynamic non-equilibrium effects of external inertial and axion fields in a system of particles with spin. The possibility of using t…
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…
Classical electrodynamics and spin-torsion coupling effects
Mariya Iv. Trukhanova, Yu. N. Obukhov
We study the Poincaré gauge theory of gravity with the most general Lagrangian quadratic in curvature and torsion, focusing on the possible interaction of the axial torsion with t…
Search for manifestations of spin-torsion coupling
Mariya Iv. Trukhanova, Pavel Andreev, Yuri N. Obukhov
We investigate the axial vector torsion-spin coupling effects in the framework of the Poincaré gauge theory of gravity with the general Yang-Mills type Lagrangian. The dynamical e…
Electric polarization evolution equation for antiferromagnetic multiferroics with the polarization proportional to the scalar product of the spins
Pavel A. Andreev, Mariya Iv. Trukhanova
The spin current model of electric polarization of multiferroics is justified via the quantum hydrodynamic method and the mean-field part of the spin-orbit interaction. The spin cu…
