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…
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…
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…
Entanglement and classical correlations at the doping-driven Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
Tools of quantum information theory offer a new perspective to characterize phases and phase transitions in interacting many-body quantum systems. The Hubbard model is the archetyp…
Specific heat maximum as a signature of Mott physics in the two-dimensional Hubbard model
G. Sordi, C. Walsh, P. Sémon +1
Recent experiments on cuprates show that as a function of doping, the normal-state specific heat sharply peaks at the doping , where the pseudogap ends at low temperature. Thi…
Critical Opalescence across the Doping Driven Mott Transition in Optical Lattices of Ultracold Atoms
C. Walsh, P. Sémon, G. Sordi +1
Phase transitions and their associated crossovers are imprinted in the behavior of fluctuations. Motivated by recent experiments on ultracold atoms in optical lattices, we compute…
