Coulomb repulsion of holes and competition between d_{x^2-y^2}-wave and s-wave parings in cuprate superconductors
V. V. Val'kov, D. M. Dzebisashvili, M. M. Korovushkin +1
The effect of the Coulomb repulsion of holes on the Cooper instability in an ensemble of spin-polaron quasiparticles has been analyzed, taking into account the peculiarities of the…
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…
Hubbard fermions band splitting at the strong intersite Coulomb interaction
Valery V. Val'kov, Maxim M. Korovushkin
The effect of the strong intersite Coulomb correlations on the formation of the electron structure of the t-V-model has been studied. A qualitatively new result has been obtained w…
