Resilient strange metal at an unconventional quantum critical point in
Jérôme Leblanc, A. -M. S. Tremblay
Properties of the two-dimensional Hubbard model with nearest-neighbor hopping are under scrutiny in cold-atom experiments and diagrammatic quantum Monte Carlo. Given the controlled…
Charge-transfer gap size and oxygen hole content as two mechanisms controlling in the Emery model
Eleanor M. O'Callaghan, Nicolas Kowalski, A. -M. S. Tremblay +1
Investigating the drivers of superconducting critical temperature trends in cuprates is crucial for uncovering the mechanism of high-temperature superconductivity. Here we study th…
Correlation of maximum superconducting critical temperature with copper-oxygen energy distance and oxygen hole content in the Emery model
Eleanor M. O'Callaghan, Nicolas Kowalski, A. -M. S. Tremblay +1
Identifying microscopic parameters that optimize the maximum superconducting critical temperature in the canonical model of the copper-oxygen plane of cuprates, the…
Pseudogap, Fermi liquid, Van Hove singularity and maxima of the compressibility and of the Knight shift as a function of doping in the two-dimensional Hubbard model
Y. M. Vilk, A. -M. S. Tremblay
Qualitative changes in thermodynamic and single-particle properties characterize the transition between the pseudogapped electronic liquid and the Fermi liquid. Recent cold-atom ex…
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…
