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 nontrivial ground state topology in the coexistence phase of chiral d-wave superconductivity and 120 degrees magnetic order on a triangular lattice
Valery V. Val'kov, Anton O. Zlotnikov, Maxim S. Shustin
The Z2 topological invariant is defined in the chiral d-wave superconductor having a triangular lattice in the presence of the 120 degrees magnetic ordering. By analyzing the Z2 in…
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…
