Mean-field approximation for a model HTSC cuprate

Alexander S. Moskvin, Yu. D. Panov

In the framework of the charge triplet model and S = 1 pseudospin formalism, we used the mean field ap- proximation typical of spin-magnetic systems to construct a phase diagram for HTSC cuprates

Monte Carlo simulation of a model cuprate

Yu. D. Panov, Alexander S. Moskvin, A. A. Chikov +1 more

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 with a high T c . A model description takes into account both local and nonlocal correlations, Heisenberg spin-exchange interaction, correlated single-particle, and two-particle transport. We formulate a state selection algorithm for a given parameterization of the wave function in order to ensure a uniform distribution of states in the phase space. The simulation results show a qualitative agreement with the experimental phase diagrams.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 with a high T c .

Classical Monte Carlo algorithm for simulation of a pseudospin model for cuprates

V. A. Ulitko, Yu. D. Panov, A. S. Moskvin

A classical Monte Carlo algorithm based on the quasi-classical approximation is applied to the pseudospin Hamiltonian of the model cuprate. The model takes into account both local and non-local correlations, Heisenberg spin-exchange interaction, single-particle and correlated two-particle transfer. We define the state selection rule that gives both the uniform distribution of states in the phase space and the doped charge conservation. The simulation results show a qualitative agreement of a phase diagrams with the experimental ones.A classical Monte Carlo algorithm based on the quasi-classical approximation is applied to the pseudospin Hamiltonian of the model cuprate.
