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

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