We consider phase transitions in chiral magnets using the results of classical Monte Carlo calculations. As the model, we consider the spin-lattice Hamiltonian of a classical spin system, in which the exchange interaction between spin and the Dzyalos

Using classical Monte Carlo simulation we investigate the evolution of the specific heat in chiral magnets with impurities. Our calculations are made in the framework of a spin lattice model and could be applicable to an analysis of the specific heat

We present new results for the system with two species of vector bosons in an optical lattice. In addition to the standard parameters characterizing such a system, we are dealing here with the ‘degree of atomic nonidentity’, manifesting itself in

Using classical Monte Carlo simulation, we investigate conditions for the occurrence of Vollhardt invariance in chiral magnets. We consider a classical spin-lattice model with exchange and Dzyaloshinskii-Moriya (DM) interaction in a magnetic field. W

We consider the evolution of the spectral function of charge carriers for a 2D Kondo lattice depending on the parameters of the model. A self-consistent solution is obtained for the spectral function using the formalism of irreducible Green’s funct

We analyze the possible types of ordering in a boson--fermion model. The Hamiltonian is inherently related to the Bose--Hubbard model for vector two-species bosons in optical lattices. We show that such model can be reduced to the Kugel--Khomskii typ

We use classical Monte Carlo calculations to model the high-pressure behavior of the phase transition in the helical magnets. We vary values of the exchange interaction constant J and the Dzyaloshinskii-Moriya interaction constant D , which is equiva
