Phase transition in the three-dimensional model: a Monte Carlo study
A. O. Sorokin
Using Monte Carlo simulations, we consider the lattice version of the sigma model for and . We find a continuous transition for $N\…
First-order and pseudo-first-order transition in the high dimensional model
A. O. Sorokin
Using the renormalization group approach, we consider the model in four and more dimensions. We find that independently on and , for , a tr…
Triple helix vs. skyrmion lattice in two-dimensional non-centrosymmetric magnets
V. E. Timofeev, A. O. Sorokin, D. N. Aristov
It is commonly assumed that a lattice of skyrmions, emerging in two-dimensional non-centrosymmetric magnets in external magnetic fields, can be represented as a sum of three magnet…
Towards an effective theory of skyrmion crystals
V. E. Timofeev, A. O. Sorokin, D. N. Aristov
We consider multiskyrmion configurations in 2D ferromagnets with Dzyaloshinskii-Moriya (DM) interaction and the magnetic field, using the stereographic projection method. In the ab…
Topological defects and critical phenomena in two-dimensional frustrated helimagnets
A. O. Sorokin
Using a simple model of a frustrated helimagnet, the critical behavior is numerically investigated for planar or isotropic spins, and for cases of one or two chiral order parameter…
Interaction of domain walls and vortices in the two-dimensional O(2) and O(3) principal chiral models
A. O. Sorokin
Using extensive Monte Carlo simulations, we investigate the critical properties of domain walls, vortices and vortices in the Ising- and Ising-$O(3)\otimes O(2…
