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…
Pseudogap and high-temperature superconductivity from weak to strong coupling. Towards quantitative theory
A. -M. S. Tremblay, B. Kyung, D. Sénéchal
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 an…
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…
Strong- and weak-coupling mechanisms for pseudogap in electron-doped cuprates
V. Hankevych, B. Kyung, A-M. Dare +2
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…
