Query: Enhanced Josephson tunneling between high temperature superconductors
  through a normal pseudogap underdoped cuprate with a finite energy cooperon   The Josephson coupling between optimally cuprate superconductors separated by
a spacer with a finite energy cooperon excitation which contributes to the
Josephson coupling strength, is examined. For an underdoped cuprate barrier in
its normal state, the YRZ model gives a good description of the temperature
dependent enhanced Josephson coupling. A detailed examination of origin of the
enhancement shows a significant contribution from the cooperon excitation which
is comparable to that from nodal quasiparticles.
