Finite range model interaction potential for d-wave superconductors: Tc versus doping in the cuprates

We study a simple, BCS like, model which describes unconventional superconductivity on the basis of an electron-electron attraction corresponding to the delta-shell potential: U( r 12)=− gδ( r 12− r 0). It predicts a T c versus doping behavior similar to that characteristic of the high T c cuprates....
