The influence of local correlations on the phase states in the model of semi-hard-core bosons on a square lattice
V. A. Ulitko, V. V. Konev, A. A. Chikov +1
The work considers a model of charged "semi-hard-core" bosons on a square lattice with a possible filling number at each node, ranging from 0 to 2. Temperature phase diagrams of th…
Competition between the Spin and Pseudospin Subsystems in a Model Cuprate
Yu. D. Panov, V. A. Ulitko, K. S. Budrin +2
The competition between the magnetic and charge orderings in a model cuprate is considered in terms of a simplified static 2D spin-pseudospin model. This model is equivalent to the…
The Parallel Monte Carlo Algorithm Implementation on GPU for the Systems with an Ising Hamiltonian under the Condition of a Constant Charge Density
K. S. Budrin, V. A. Ulitko, A. A. Chikov +2
This paper is devoted to computational algorithms designed to describe the classical Ising magnet in some specific cases when an additional macroscopic restriction in form of const…
Monte Carlo simulation of a model cuprate
Yu. D. Panov, A. S. Moskvin, A. A. Chikov +1
We develop a classical Monte Carlo algorithm based on a quasi-classical approximation for a pseudospin S=1 Hamiltonian in real space to construct a phase diagram of a model cuprate…
Critical behavior of a 2D spin-pseudospin model in a strong exchange limit
D. N. Yasinskaya, V. A. Ulitko, A. A. Chikov +1
We study the 2D static spin-pseudospin model equivalent to the dilute frustrated antiferromagnetic Ising model with charge impurities. We present the results of classical Monte Car…
Phase diagrams of a 2D Ising spin-pseudospin model
Yu. D. Panov, V. A. Ulitko, K. S. Budrin +2
We consider the competition of magnetic and charge ordering in high-Tc cuprates within the framework of the simplified static 2D spin-pseudospin model. This model is equivalent to…
