“…The k dependent symmetry of the pairing interaction kernel C kk 0 effects the gap symmetry which is corroborated by many experiments on cuprates, indicating a d x 2 Ày 2 -wave gap D k / cosðk x Þ À cosðk y Þ [7,9,10]. Although a d-wave gap accounts for some k dependent observed HTS properties, symmetry factors do not account for the large gaps and critical temperatures in cuprate HTS [10], nor do they significantly effect thermodynamic properties that represent k -space averages.…”

a b s t r a c tA pairing Hamiltonian HðCÞ with an interaction kernel C characterized by ½ÀC 0 ; Àa 0 , where C 0 denotes the separable part and a 0 the degree of non-separability, produces high temperature superconductivity for both attractive C 0 > 0 and repulsive C 0 < 0 when a 0 > 0. For C 0 > 0, typical HTS properties, e.g. cuprate, are produced. Repulsive C 0 < 0 produces a distinct difference in the kinetic energy dependence of the SC gap, significantly altering thermodynamic properties.

“…In particular, it is true for d-wave superconductors, where the order parameter changes its sign on the Fermi surface (FS) [119,[138][139][140][141][142][143]. As was indicated above, high-T c oxides are usually considered as such materials, where the d x 2 −y 2 pairing is usually assumed at least as a dominating one [117,[144][145][146][147][148][149][150][151][152]. However, conventional s-wave contributions were also detected in electron tunneling experiments [153][154][155][156][157][158][159][160] and, probably, in nuclear magnetic resonance (NMR) and nuclear quadrupole resonance measurements [161].…”

“…This question remains unanswered, although the majority of the researchers in the field think believe that the problem is already resolved (namely, d x 2 −y 2 -one, see, e.g., Refs. [54,90])? (iv) What is the role of the intrinsic disorder and non-stoichiometry in the superconducting properties [2,28,43,69,70,75,103,105]?…”
