Journal ArticleDOI
Bethe-Salpeter eigenvalues and amplitudes for the half-filled two-dimensional Hubbard model.
TL;DR: Monte Carlo simulations are used to determine the eigenvalues and eigenfunctions of the particle-hole and particle-particle Bethe-Salpeter equations for 8×8 half-filled Hubbard lattice with U/T=4 and U/t=8.
Journal ArticleDOI
Checkerboard patterns in the t-J model
TL;DR: In this article, the authors studied the possibility of real space checkerboard patterns arising as the ground states of the t-J model and found that checkerboards with a commensurate (pi,pi) background are not low energy states and can only be stabilized with large external potentials.
Journal ArticleDOI
Ground-state properties of the periodic Anderson model
TL;DR: The ground-state energy, hybridization matrix element, local moment, and spin-density correlations of a one-dimensional, finite-chain, periodic, symmetric Anderson model are obtained and compared with perturbation theory and strong-coupling results are compared.
Journal ArticleDOI
Coherent states and particle production
TL;DR: In this article, it was shown that for a wide variety of configurations of the pion field density operator, the density operator can be written in diagonal form in the coherent-state representation.
Journal ArticleDOI
Charge and spin structures of a d x 2 − y 2 superconductor in the proximity of an antiferromagnetic Mott insulator
TL;DR: In this paper, the authors used zero-temperature quantum Monte Carlo simulations on lattice sizes up to 16 × 16 to show that at half-filling and constant value of the Hubbard repulsion, the interaction $W$ triggers a quantum transition between an antiferromagnetic Mott insulator and a superconductor.
