Charge and Spin Structures of a Superconductor in the Proximity of an Antiferromagnetic Mott Insulator
F. F. Assaad, M. Imada, D. J. Scalapino
To the Hubbard model on a square lattice we add an interaction, , which depends upon the square of a near-neighbor hopping. We use zero temperature quantum Monte Carlo simulatio…
Quantum Transition between an Antiferromagnetic Mott Insulator and Superconductor in Two Dimensions
F. F. Assaad, M. Imada, D. J. Scalapino
We consider a Hubbard model on a square lattice with an additional interaction, , which depends upon the square of a near-neighbor hopping. At half-filling and a constant value…
Insulator-Metal Transition in the One and Two-Dimensional Hubbard Models
F. F. Assaad, M. Imada
We use Quantum Monte Carlo methods to determine Green functions, , on lattices up to for the 2D Hubbard model at . For chemical potentia…
Stable Quantum Monte Carlo Algorithm for Calculation of Imaginary Time Green Functions
F. F. Assaad, M. Imada
We present a numerically stable Quantum Monte Carlo algorithm to calculate zero-temperature imaginary-time Green functions for Hubbard type models. We illustrate…
