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…
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…
