Summary
Denis D. Sheka. Vortices in Two-Dimensional Easy-Plane
Magnets. Dynamics, Relaxation, and Contribution to the Magnet Response
Functions.
Theoretical description of in-plane and out-of-plane vortex dynamics for
weakly- and highly-anisotropical 2D ferro- and antiferromagnets is
presented. The vortex phenomenology for the topological phase transition of
Berezinskii-Kosterlitz-Thouless type is extended. The vortex gas
contribution to the response functions of 2D magnets is considered.
