The Two-Particle Self-Consistent Approach for Multiorbital models: application to the Emery model
C. Gauvin-Ndiaye, J. Leblanc, S. Marin +3
The Emery model, or three-band Hubbard model, is a Hamiltonian that is thought to contain much of the physics of cuprate superconductors. This model includes two noninteracting …
Spin Hall conductivity in the Kane-Mele-Hubbard model at finite temperature
D. Lessnich, C. Gauvin-Ndiaye, Roser Valentí +1
The Kane-Mele model is known to show a quantized spin Hall conductivity at zero temperature. Including Hubbard interactions at each site leads to a quantum phase transition to an X…
An Improved Two-Particle Self-Consistent Approach
C. Gauvin-Ndiaye, C. Lahaie, Y. M. Vilk +1
The two-particle self-consistent approach (TPSC) is a method for the one-band Hubbard model that can be both numerically efficient and reliable. However, TPSC fails to yield physic…
Nonlocal corrections to dynamical mean-field theory from the two-particle self-consistent method
N. Martin, C. Gauvin-Ndiaye, A. -M. S. Tremblay
Theoretical methods that are accurate for both short-distance observables and long-wavelength collective modes are still being developed for the Hubbard model. Here, we benchmark a…
Disorder effects on hot spots in electron-doped cuprates
C. Gauvin-Ndiaye, P. -A. Graham, A. -M. S. Tremblay
Antiferromagnetic fluctuations in two dimensions cause a decrease in spectral weight at so-called hot spots associated with the pseudogap in electron-doped cuprates. In the 2D Hubb…
Resilient Fermi liquid and strength of correlations near an antiferromagnetic quantum critical point
C. Gauvin-Ndiaye, M. Setrakian, A. -M. S. Tremblay
Near the antiferromagnetic quantum critical point (QCP) of electron-doped cuprate superconductors, angle-resolved photoemission experiments detect hot spots where the Fermi surface…
