Title: Quantum Transition between an Antiferromagnetic Mott Insulator and {ital d}{sub {ital x}{sup 2} {minus}{ital y}{sup 2}} Superconductor in Two Dimensions

Abstract

We consider a Hubbard model on a square lattice with an additional interaction, {ital W}, which depends upon the square of the near-neighbor hopping. At half filling and a constant value of the Hubbard repulsion, increasing the strength of the interaction {ital W} drives the system from an antiferromagnetic Mott insulator to a {ital d}{sub {ital x}{sup 2}{minus}{ital y}{sup 2}} superconductor. This conclusion is reached on the basis of zero temperature quantum Monte Carlo simulations on lattice sizes up to 16{times}16. {copyright} {ital 1996 The American Physical Society.}
