Symmetry of the superconducting gap function from electron scattering by interacting tunneling units
The symmetry of the gap function is derived for a system in which the conduction electrons are scattered by elastically interacting tunneling units, causing pairing and superconductivity. For specific examples of tunneling units found in experiments on a number of high T c materials we obtain; (i) a...
