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…
The classical-quantum disproportionation transition and magnetic ordering in RNiO nickelates
A. S. Moskvin, Yu. D. Panov
The insulator-quasi-metal (bad metal) transition observed in Jahn-Teller (JT) magnets orthonickelates RNiO (R = rare earth, or yttrium Y) is considered a canonical example of t…

The Monte Carlo Method for the Orthonickelate Model
Yu. D. Panov, S. V. Nuzhin, V. S. Ryumshin +1
The peculiarities of phase states of the triplet boson model for orthonickelates are investigated analytically and by means of numerical simulations. The conditions of thermodynami…
The mean field approximation for a system of triplet bosons in nickelates
V. S. Ryumshin, S. V. Nuzhin, Yu. D. Panov +1
Rare-earth orthonickelates RNiO3 are Jahn-Teller magnets, unstable with respect to the anti-Jahn-Teller disproportionation reaction with the formation of a system equivalent to a s…
