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…
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…
Non-Fermi liquid phase and linear-in-temperature scattering rate in overdoped two dimensional Hubbard model
Wei Wu, Xiang Wang, A. -M. S. Tremblay
Understanding electronic properties that violate the Landau Fermi liquid paradigm in cuprate superconductors remains a major challenge in condensed matter physics. The strange meta…
Information-theoretic measures of superconductivity in a two-dimensional doped Mott insulator
C. Walsh, M. Charlebois, P. Sémon +2
A key open issue in condensed matter physics is how quantum and classical correlations emerge in an unconventional superconductor from the underlying normal state. We study this pr…
Accelerated impurity solver for DMFT and its diagrammatic extensions
Corey Melnick, Patrick Sémon, Kwangmin Yu +3
We present ComCTQMC, a GPU accelerated quantum impurity solver. It uses the continuous-time quantum Monte Carlo (CTQMC) algorithm wherein the partition function is expanded in term…
Mott transition and high-temperature crossovers at half-filling
A. Reymbaut, M. Boulay, L. Fratino +4
The interaction-driven Mott transition in the half-filled Hubbard model is a first-order phase transition that terminates at a critical point in the t…
Intrinsic Cluster-Shaped Density Waves in Cellular Dynamical Mean-Field Theory
S. Verret, J. Roy, A. Foley +3
It is well known that cellular dynamical mean-field theory (CDMFT) leads to the artificial breaking of translation invariance. In spite of this, it is one of the most successful me…
Thermodynamic and information-theoretic description of the Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
At the Mott transition, electron-electron interaction changes a metal, in which electrons are itinerant, to an insulator, in which electrons are localized. This phenomenon is centr…
Entanglement entropy and mutual information across the Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
Entanglement and information are powerful lenses to probe phases transitions in many-body systems. Motivated by recent cold atom experiments, which are now able to measure the corr…
First order Mott transition at zero temperature in two dimensions: Variational plaquette study
Matthias Balzer, Bumsoo Kyung, David Sénéchal +2
The nature of the metal-insulator Mott transition at zero temperature has been discussed for a number of years. Whether it occurs through a quantum critical point or through a firs…
Anomalous superconductivity and its competition with antiferromagnetism in doped Mott insulators
S. S. Kancharla, B. Kyung, D. Senechal +4
Proximity to a Mott insulating phase is likely to be an important physical ingredient of a theory that aims to describe high-temperature superconductivity in the cuprates. Quantum…

Using the two-particle self-consistent approach and cluster perturbation theory for the two-dimensional t-t'-t''-U Hubbard model, we discuss weak- and strong-coupling mechanisms fo…

S. Allen, A. -M. S. Tremblay
A non-perturbative approach to the single-band attractive Hubbard model is presented in the general context of functional derivative approaches to many-body theories. As in previou…
