Scaling and commensurate-incommensurate crossover for the d=2, z=2 quantum critical point of itinerant antiferromagnets
Sébastien Roy, A. -M. S. Tremblay
Quantum critical points exist at zero temperature, yet, experimentally their influence seems to extend over a large part of the phase diagram of systems such as heavy-fermion compo…
Quantum Monte Carlo Study of Strongly Correlated Electrons: Cellular Dynamical Mean-Field Theory
B. Kyung, G. Kotliar, A. -M. S. Tremblay
We study the Hubbard model using the Cellular Dynamical Mean-Field Theory (CDMFT) with quantum Monte Carlo (QMC) simulations. We present the algorithmic details of CDMFT with the H…
Nearest-Neighbor Repulsion and Competing Charge and Spin Order in the Extended Hubbard Model
B. Davoudi, A. -M. S. Tremblay
We generalize the two-particle self-consistent approach (TPSC) to study the extended Hubbard model, where nearest-neighbor interaction is present in addition to the usual local scr…
Weak ferromagnetism and other instabilities of the two-dimensional t-t' Hubbard model at Van Hove fillings
V. Hankevych, B. Kyung, A. -M. S. Tremblay
We investigate magnetic and superconducting instabilities of the two-dimensional t-t' Hubbard model on a square lattice at Van Hove densities from weak to intermediate coupling by…
