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…
Prediction of Large Magnetic Moment Materials With Graph Neural Networks and Random Forests
Sékou-Oumar Kaba, Benjamin Groleau-Paré, Marc-Antoine Gauthier +3
Magnetic materials are crucial components of many technologies that could drive the ecological transition, including electric motors, wind turbine generators and magnetic refrigera…
Analysis of the magnetic and magnetocaloric properties of ALaFeMnO6 (A= Sr, Ba and Ca) double perovskites
N. Brahiti, M. Abbasi Eskandari, M. Balli +4
In previous studies, we have reported that double perovskite La2NiMnO6 presents a non-negligible potential for room temperature magnetocaloric tasks. With the aim of improving even…
Electronic and Magnetic Properties of the Candidate Magnetocaloric-Material Double Perovskites LaMnCoO, LaMnNiO and LaMnFeO
C. Gauvin-Ndiaye, T. E. Baker, P. Karan +7
The search for room-temperature magnetocaloric materials for refrigeration has led to investigations of double perovskites. In particular, a puzzle has appeared in the LaMnNiO$…
Electronic and Magnetic Properties of double-perovskites LaMnRuO and Hole-Doped LaMnFeO and their Potential for Magnetic Refrigeration
C. Gauvin-Ndiaye, A. -M. S. Tremblay, R. Nourafkan
Magnetic refrigeration at room-temperature is a technology that could potentially be more environmentally-friendly, efficient and affordable than traditional refrigeration. The sea…
