A Theoretical Approach to Pseudogap and Superconducting Transitions in Hole-Doped Cuprates
Table 1
The values of the pseudo-gap (PG) state entropy given by (36) (column (ii)) and the normal state entropy given by (37) (column (iv)) at the temperatures indicated at the doping level 9.94%. We also have noted the values of calculated using (38). We identify the pseudo-gap temperature (~200 K) as the one at which the entropy difference becomes zero. The entropy is almost a smoothly increasing function of temperature. There appears to be a small discontinuity (not clearly discernable) in entropy at during the passage from the PG state to normal state. We find that there is no discontinuity in the electronic specific heat either.
