Towards an effective theory of skyrmion crystals
V. E. Timofeev, A. O. Sorokin, D. N. Aristov
We consider multiskyrmion configurations in 2D ferromagnets with Dzyaloshinskii-Moriya (DM) interaction and the magnetic field, using the stereographic projection method. In the ab…
Topological defects and critical phenomena in two-dimensional frustrated helimagnets
A. O. Sorokin
Using a simple model of a frustrated helimagnet, the critical behavior is numerically investigated for planar or isotropic spins, and for cases of one or two chiral order parameter…
Interaction of domain walls and vortices in the two-dimensional O(2) and O(3) principal chiral models
A. O. Sorokin
Using extensive Monte Carlo simulations, we investigate the critical properties of domain walls, vortices and vortices in the Ising- and Ising-$O(3)\otimes O(2…
Critical density of topological defects upon a continuous phase transition
A. O. Sorokin
Using extensive Monte Carlo simulations, we test the hypothesis that the density of corresponding topological defects has an universal value at the temperature of a continuous phas…
