A Theoretical Approach to Pseudogap and Superconducting Transitions in Hole-Doped Cuprates

Figure 1

A generic phase diagram of the hole-doped cuprates in the doping level (𝑥)-temperature (𝑇) plane. The antiferromagnetic phase corresponds to the blackened region in the far left. While the lightly red region to its right is the pseudogap (PG) state, the near-semicircular red region corresponds to the superconducting (SC) phase. The curves 𝑇^∗(𝑥) and 𝑇_𝑐(𝑥), respectively, correspond to the PG transition (from the paramagnetic insulating phase) and the SC transition. The vertical, thick green line within the SC phase corresponds to the region investigated which is a part of the superconducting DDW region.
