A pairing Hamiltonian H(Γ) with an interaction kernel Γ characterized by [-^Γ0,-^α0], where ^Γ0 denotes the separable part and ^α0 the degree of non-separability, produces high temperature superconductivity for both attractive ^Γ0>0 and repulsive ^Γ0<0 when ^α0>0. For ^Γ0>0, typical HTS properties, e.g. cuprate, are produced. Repulsive ^Γ0<0 produces a distinct difference in the kinetic energy dependence of the SC gap, significantly altering thermodynamic properties.
