Stability of the d-wave pairing with respect to the intersite Coulomb repulsion in cuprate superconductors
V. V. Val'kov, D. M. Dzebisashvili, M. M. Korovushkin +1
Within the spin-fermion model for cuprate superconductors, the influence of the intersite Coulomb interactions and between holes located at the next-nearest-neighbor o…
Effective indirect multi-site spin-spin interactions in the s-d(f) model
K. K. Komarov, D. M. Dzebisashvili
Using the diagram technique for Matsubara Green's functions it is shown that the dynamics of the localized spin subsystem in the s-d(f) model can be described in terms of an effect…
The generalized Kondo lattice model and its spin-polaron implementation for cuprates by projection method
V. V. Val'kov, D. M. Dzebisashvili, A. F. Barabanov
It is shown that the spin-fermion model found to be an effective low-energy implementation of the three-band Emery model after Wannier transformation of - and -orbitals i…
Stability of the superconducting -wave pairing towards the intersite Coulomb repulsion between oxygen holes in high-T superconductors
V. V. Val'kov, D. M. Dzebisashvili, M. M. Korovushkin +1
It is shown that an account for the space separatedness of the two-orbital subsystem of the oxygen holes and the subsystem of the localized spins of copper ions in high-T cupra…
