Phys. Rev. Lett. 95, 237001 (2005) [4 pages]Systematic Study of d-Wave Superconductivity in the 2D Repulsive Hubbard ModelReceived 20 April 2005; published 29 November 2005 The cluster size dependence of superconductivity in the conventional two-dimensional Hubbard model, commonly believed to describe high-temperature superconductors, is systematically studied using the dynamical cluster approximation and quantum Monte Carlo simulations as a cluster solver. Because of the nonlocality of the d-wave superconducting order parameter, the results on small clusters show large size and geometry effects. In large enough clusters, the results are independent of the cluster size and display a finite temperature instability to d-wave superconductivity. © 2005 The American Physical Society URL:
