Abstract

We develop an algorithm which employs the projective quantum Monte
Carlo method for solving the equations of the dynamical cluster
approximation at zero temperature, and apply it for studying pair
susceptibilities of the two-dimensional Hubbard-model with next-nearest
neighbor hopping. In particular, we identify which pairing symmetry is
dominant in the U-n parameter space (U: repulsive Coulomb interaction;
n: electron density). We find that p(x+y)(-)(d(x)(2)-y(2-)) wave is
dominant among triplet (singlet) pairings-at least for 0.3 < n < 0.8
and U <= 4t. The crossover between d(x)(2)-y(2-) wave and p(x+y)(-)
wave occurs around n similar to 0.4.
