Broad Peak in the d_{x^2-y^2} Superconducting Correlation Length as a Function of Hole Concentration in the Two-Dimensional t-J Model

W. O. Putikka, M. U. Luchini

We have calculated high temperature series to 12th order in inverse temperature for singlet superconducting correlation functions of the 2D t-J model with s-, d_{x^2-y^2}- and d_xy…
