The phase diagram of high-T-c superconductors in the presence of dynamic stripes

The phase diagram of superconducting copper oxides is calculated as a funct ion of doping on the basis of a theory of dynamic stripe-induced supercondu ctivity. The two major conclusions from the theory and the numerical analys is are that T-* (the pseudogap onset temperature) and T, (the superconducti vity onset temperature) are correlated through the pseudogap, which induces a gap in the single-particle energies that persists into the superconducti ng state. On decreasing the doping the pseudogap hr increases and T-* incre ases, but when Delta (*) exceeds a certain critical value the superconducti ng transition temperature T-c is lowered. A mixed s- and d-wave pairing sym metry is also examined as a function of doping.
