Arbitrary number of thermally induced phase transitions in different universality classes in models with higher-order terms
Milan ŽukoviÄ
We propose generalized variants of the model capable of exhibiting an arbitrary number of phase transitions only by varying temperature. They are constructed by supplementing…
Frustration-driven topological textures on the honeycomb lattice: antiferromagnetic meron-antimeron and skyrmion crystals emerging from spiral spin liquids
M. Mohylna, F. A. Gómez AlbarracÃn, M. ŽukoviÄ +1
Skyrmions -- topologically nontrivial magnetic quasi-particles -- can emerge in two-dimensional chiral magnets due to moderate or high strength of the Dzyaloshinskii-Moriya (DM) in…
Crossover from BKT to first-order transition induced by higher-order terms in 2D XY models
Milan ŽukoviÄ
We study phase transitions in models, generalized by inclusion of higher-order pairwise interactions of equal strength, by Monte Carlo simulation. It is found that by addi…
Generalized model with competing antiferromagnetic and antinematic interactions
Milan ŽukoviÄ
We study effects of -order antinematic (AN) interactions on the critical behavior of the antiferromagnetic (AF) model on a square lattice. It is found that the evolutio…
