The binding energies of excess carriers (holes or electrons) as functions of the in-plane copper-oxygen hopping matrix element are calculated numerically by an exact diagonalization of the Emery Hamiltonian for the two-dimensional Cu408 cluster. Based on the results of the calculations, a qualitativ
The purpose of this paper is to explain the unusual isotope coefficients of cuprates by considering the influence of a pseudogap and phononic and electronic interactions in weak-coupling limit. Exact analytic expressions of the isotope exponent (a) for the s-and d-wave pairing symmetry are derived.
