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…
Improved effective vertices in the multi-orbital Two-Particle Self-Consistent method from Dynamical Mean-Field Theory
Karim Zantout, Steffen Backes, Aleksandar Razpopov +2
In this work we present a multi-orbital form of the Two-Particle Self-Consistent approach (TPSC), here the effective local and static irreducible interaction vertices are determine…
Elementary band representations for the single-particle Green's function of interacting topological insulators
Dominik Lessnich, Stephen M. Winter, Mikel Iraola +2
We discuss the applicability of elementary band representations (EBRs) to diagnose spatial- and time-reversal-symmetry protected topological phases in interacting insulators in ter…
Towards a Topological Quantum Chemistry description of correlated systems: the case of the Hubbard diamond chain
Mikel Iraola, Niclas Heinsdorf, Apoorv Tiwari +9
The recently introduced topological quantum chemistry (TQC) framework has provided a description of universal topological properties of all possible band insulators in all space gr…
