Phys. Rev. Lett. 70, 682–685 (1993)Indications of dx2-y2 superconductivity in the two dimensional t-J modelReceived 13 October 1992; published in the issue dated 1 February 1993 Supercomputing correlations in the two dimensional t-J model at zero temperature are evaluated using numerical techniques. At the fermionic density 〈n〉∼1/2, strong signals of dx2-y2 superconductivity were observed in the ground state. These conclusions are based on a study of static pairing correlations, the Meissner effect, and flux quantization as indicators of superconductivity. A tentative phase diagram of the two dimensional t-j model is presented. © 1993 The American Physical Society URL:
