Phys. Rev. Lett. 69, 168–171 (1992)Hubbard model in infinite dimensions: A quantum Monte Carlo studyReceived 5 December 1991; published in the issue dated 6 July 1992 An essentially exact solution of the infinite-dimensional Hubbard model is made possible by a new self-consistent Monte Carlo procedure. Near half filling antiferromagnetism and a pseudogap in the single-particle density of states are found for sufficiently large values of the intrasite Coulomb interaction. At half filling the antiferromagnetic transition temperature obtains its largest value when the intrasite Coulomb interaction U≊3. © 1992 The American Physical Society URL:
