Excitonic insulators and Gross-Neveu models
Nei Lopes, Mucio A. Continentino, Daniel G. Barci
We introduce a generalized Gross-Neveu (GN) model to describe the excitonic instabilities in two different systems: a small overlap semi-metal (SM) and a small gap semi-conductor (…

Interplay between charge density wave and superconductivity in multi-band systems with inter-band Coulomb interaction
Nei Lopes, Daniel Reyes, Mucio A. Continentino +1
In this work we study the competition or coexistence between charge density wave (CDW) and superconductivity (SC) in a two-band model system in a square lattice. One of the bands h…
