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…
