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…
Influence of Local Correlations on the "Homogeneous Insulator-Superconductor" Transition in the Domain Boundaries of the Charge-Order Phase of a 2D System of a Mixed Valence
V. V. Konev, V. A. Ulitko, D. N. Yasinskaya +2
It is demonstrated in the (pseudo)spin S=1 formalism that the structure of antiphase domain boundaries in the phase of charge ordering of a mixed-valence system of the Cu1+, 2+, 3+…
Features of the Domain Boundaries of a Highly Anisotropic (S = 1) Antiferromagnet near the Transition to the Quantum Paramagnet Phase
V. V. Konev, V. A. Ulitko, D. N. Yasinskaya +2
It is shown that the structure of antiphase domain boundaries in the antiferromagnetic (AFM) phase of a highly anisotropic magnet with S = 1 on a two-dimensional square lattice dep…
The MFA ground states for the extended Bose-Hubbard model with a three-body constraint
Yu. D. Panov, A. S. Moskvin, E. V. Vasinovich +1
We address the intensively studied extended bosonic Hubbard model (EBHM) with truncation of the on-site Hilbert space to the three lowest occupation states n=0,1,2 in frames of the…
