Coexistence of superconductivity and charge density wave in a correlated regime
E. J. Calegari, L. C. Prauchner, A. C. Lausmann +1
To investigate the coexistence of superconductivity and charge density wave (CDW) in a correlated regime, we employ the Green's functions formalism, as well as the Hubbard-I approx…

Interplay between the charge density wave phase and a pseudogap under antiferromagnetic correlations
Leonardo Prauchner, Eleonir Calegari, Julian Faundez +1
In this study, we explore the impact of short-range antiferromagnetic correlations on the charge density wave (CDW) phase in strongly correlated electron systems exhibiting the pse…

The interplay between a pseudogap and superconductivity in a two-dimensional Hubbard model
L. F. Sampaio, E. J. Calegari, J. J. RodrÃguez-Núñez +2
Strongly correlated electrons systems may exhibit a variety of interesting phenomena, for instance, superconductivity and pseudogap, as is the case of cuprates and pnictides. In st…
