Modified Monte Carlo method with the heat bath algorithm for a model cuprate
Yu. D. Panov, V. A. Ulitko, D. N. Yasinskaya +1
The results of numerical simulation using a modified Monte Carlo method with a heat bath algorithm for the pseudospin model of cuprates are presented. The temperature phase diagram…
Anti-Jahn-Teller disproportionation and prospects for spin-triplet superconductivity in d-element compounds
A. S. Moskvin, Yu. D. Panov
We argue that the unusual properties of a wide class of materials based on Jahn-Teller 3d and 4d ions with different crystal and electronic structures, from quasi-two-dimensional u…
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+…
Phase separation in high-T cuprates
A. S. Moskvin, Yu. D. Panov
We develop a minimal non-BCS model for the CuO planes with the on-site Hilbert space reduced to only three effective valence centers CuO with different charge, conventional…
Model of charge triplets for high-T cuprates
A. S. Moskvin, Yu. D. Panov
Starting with a minimal model for the CuO planes with the on-site Hilbert space reduced to a charge triplet of the three effective valence centers [CuO] (nomin…
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…
Asymptotics of quasi-classical localized states in 2D system of charged hard-core bosons
Yu. D. Panov, A. S. Moskvin
The continuous quasi-classical two-sublattice approximation is constructed for the 2D system of charged hard-core bosons to explore metastable inhomogeneous states analogous to inh…
Superconductivity in model cuprate as an S=1 pseudomagnon condensation
E. V. Vasinovich, A. S. Moskvin, Yu. D. Panov
We make use of the S=1 pseudospin formalism to describe the charge degree of freedom in a model high- cuprate with the on-site Hilbert space reduced to the three effective val…
Dynamical charge inhomogeneity and crystal-field fluctuations for 4f ions in high-Tc cuprates
A. S. Moskvin, N. V. Melnikova
The main relaxation mechanism of crystal-field excitations in rare-earth ions in cuprates is believed to be provided by the fluctuations of crystalline electric field induced by a…
Vibronic Mechanism of the Isotope and Pressure Effects in Cuprates
A. S. Moskvin, Yu. D. Panov
The doped cuprates are considered to be a system of local spinless bosons moving in a lattice of the hole pseudo-Jahn-Teller centers CuO_{4}^{5-}. A detailed qualitative and quanti…
Polar Jahn-Teller Centers and Isotope Effect in Copper Oxide high-T_c-Superconductors
A. S. Moskvin, A. S. Ovchinnikov, Yu. D. Panov +1
The -cluster based copper oxides are considered as generalized quantum lattice bose-gas or a system of the local singlet bosons moving in a lattice of the hole Jahn-Teller c…
