Abstract
We consider a Hubbard model on a square lattice with an additional int eraction, W, which depends upon the square of the near-neighbor hoppin g. At half filling and a constant value of the Hubbard repulsion, incr easing the strength of the interaction W drives the system from an ant iferromagnetic Mott insulator to a d(x2-y2) superconductor. This concl usion is reached on the basis of zero temperature quantum Monte Carlo simulations on lattice sizes up to 16 x 16.
