• Effect of Local Correlations on Phase States in a Model of Semi-Hard-Core Bosons on a Square Lattice2024 · аннотациясвернуть

  The authors consider a model of charged semi-hard-core bosons on a square lattice with possible occupation number n_i = 0,1,2~ at each site. Temperature phase diagrams of the model are obtained using quantum…

• The influence of local correlations on the phase states in the model of semi-hard-core bosons on a square lattice2023 · аннотациясвернуть

  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 the model are obtained using numerical…

• Monte Carlo simulation of a model cuprate2021
• Critical Behavior of a 2D Spin-Pseudospin Model in a Strong Exchange Limit2020
• Phase diagrams of a 2D Ising spin-pseudospin model2019
• Bethe Approximation for a Two-Dimensional Spin-Pseudospin System2019
• The Ground-State Phase Diagram of 2D Spin–Pseudospin System2017
• Unconventional spin-charge phase separation in a model 2D cuprate2017 · аннотациясвернуть

  In this work, we address a challenging problem of a competition of charge and spin orders for high-T c cuprates within a simplified 2D spin-pseudospin model which takes into account both conventional Heisenberg…
