Superconductivity in the two-dimensional Hubbard model with cellular dynamical mean-field theory: a quantum impurity model analysis
C. Walsh, M. Charlebois, P. Sémon +2
Doping a Mott insulator gives rise to unconventional superconducting correlations. Here we address the interplay between d-wave superconductivity and Mott physics using the two-dim…
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 …
Dynamical Variational Monte Carlo as a quantum impurity solver: Application to Cluster Dynamical Mean-Field Theory
P. Rosenberg, D. Sénéchal, A. -M. S. Tremblay +1
Two of the primary sources of error in the Cluster dynamical mean-field theory (CDMFT) technique arise from the use of finite size clusters and finite size baths, which makes the d…
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…
Fermi Arcs From Dynamical Variational Monte Carlo
P. Rosenberg, D. Sénéchal, A. -M. S. Tremblay +1
Variational Monte Carlo is a many-body numerical method that scales well with system size. It has been extended to study the Green function only recently by Charlebois and Imada (2…
Prediction of anomalies in the velocity of sound for the pseudogap of hole-doped cuprates
C. Walsh, M. Charlebois, P. Sémon +2
We predict sound anomalies at the doping where the pseudogap ends in the normal state of hole-doped cuprates. Our prediction is based on the two-dimensional compressible Hu…
