Research area:
The theory of nonlinear phenomena in condensed matter physics based on the soliton concept and its applications for description of nonlinear effects in solids.
Last five years activity and current interests:
Subjects of current investigations include theoretical research of the non-stationary and internal dynamics of topological solitons and conditions of formation and propagation of bound soliton complexes and breather excitations in nonlinear systems with the strong dispersion, computer simulation of the soliton-complexes nonstationary dynamics, exact theoretical description of spin waves scattering by moving domain walls in anisotropic antiferromagnets in a magnetic field, an exact solution of the problem of the stability of discrete magnetic nanostructures and the spectral problem for their localized excitations in quasi-one-dimensional ferromagnet, and construction of the theory of the local negative magnetic permeability in nonlinear low-dimensional metamaterials and revealing a possibility of observation of breather excitations in such systems.
