Dynamics of superconducting pairs in the two-dimensional Hubbard model
G. Sordi, E. M. O'Callaghan, C. Walsh +3
The frequency structure of the superconducting correlations in cuprates gives insights on the pairing mechanism. Here we present an exhaustive study of this problem in the two-dime…
The Frenkel line and the pseudogap: an analogy between classical and electronic fluids
J. Fournier, P. -O. Downey, O. Gingras +3
Asymptotically close to critical end-points of first-order transitions, maxima in thermodynamic quantities occur along a line called the Widom line, a concept first introduced in c…
Two -linear scattering rate regimes in the triangular lattice Hubbard model
Jérôme Fournier, Pierre-Olivier Downey, Charles-David Hébert +2
In recent years, the -linear scattering rate found at low temperatures, defining the strange metal phase of cuprates, has been a subject of interest. Since a wide range of mater…
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…
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…
Doping the Mott insulating state of the triangular-lattice Hubbard model reveals the Sordi transition
P. -O. Downey, O. Gingras, C. -D. Hébert +2
It has been reported that upon doping a Mott insulator, there can be a crossover to a pseudogaped metallic phase followed by a first-order transition to another thermodynamically s…
