Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

A term first coined by Mott back in 1968 a “pseudogap” is the depletion of the electronic
density of states at the Fermi level, and pseudogaps have been observed in many systems …

Electron-doped cuprates consistently exhibit strong antiferromagnetic correlations, leading
to the prevalent belief that antiferromagnetic spin fluctuations mediate Cooper pairing in …

We study the evolution of a Mott-Hubbard insulator into a correlated metal upon do** in
the two-dimensional Hubbard model using the cellular dynamical mean-field theory. Short …

Superconductors are characterized by an energy gap that represents the energy needed to
break the pairs of electrons (Cooper pairs) apart. At temperatures considerably above those …

Abstract High-transition-temperature (high-T c) superconductivity develops near
antiferromagnetic phases, and it is possible that magnetic excitations contribute to the …

In this article, I review progress towards an understanding of the normal state (in-plane)
transport properties of high-T c cuprates in the light of recent developments in both …

Using variational cluster perturbation theory we study the competition between d-wave
superconductivity (d SC) and antiferromagnetism (AF) in the tt′-t′′-U Hubbard model …

This is a short review of the theoretical work on the two-dimensional Hubbard model
performed in Sherbrooke in the last few years. It is written on the occasion of the twentieth …

We performed high-resolution angle-resolved photoemission spectroscopy on electron-
doped high-T c superconductor Pr 0.89 LaCe 0.11 CuO 4 to study the anisotropy of the …
