Temperature and doping dependence of normal state spectral properties in a two-orbital model for ferropnictides
J. D. Querales Flores, C. I. Ventura, R. Citro +1
Using a second-order perturbative Green's functions approach we determined the normal state single-particle spectral function employing a minimal effective model for…
Two-bands superconductivity with intra- and interband pairing for synthetic superlattices
Alex A. Schmidt, Jose J. Rodríguez-Núñez, Antonio Bianconi +1
We consider a model for superconductivity in a two-band superconductor, having an anisotropic electronic structure made of two partially overlapping bands with a first hole-like an…
Evidence for a metallic--like state in the T=0 K phase diagram of a high temperature superconductor
A. A. Schmidt, J. J. Rodriguez-Nunez, I. Tifrea
We examine the effects of a phenomenological pseudogap on the T=0 K phase diagram of a high temperature superconductor within a self-consistent model which exhibits a d-wave pairin…
Ginzburg-Landau Expansion in Non-Fermi Liquid Superconductors: Effect of the Mass Renormalization Factor
I. Tifrea, J. A. Budagosky Marcilla, J. J. Rodriguez-Nunez
We reconsider the Ginzburg-Landau expansion for the case of a non-Fermi liquid superconductor. We obtain analytical results for the Ginzburg-Landau functional in the critical regio…
Some sum rules for the non-Fermi liquids: new applications taking into account the mass renormalization factor
J. J. Rodriguez-Nunez, I. Tifrea, S. G. Magalhaes
Re-studying the non-fermi liquid one-particle Green function (NFLGF) we have extended the work of A. Balatsky (Phil. Mag. Lett. 68, 251 (1993)) and L. Yin and S. Chakravarty (Int.…
Beyond the Hubbard-I Solution with a One-Pole Self-Energy at Half-Filling with the Moment Approach: Non-Linear Effects
J. J. Rodriguez-Nunez, M. A. de Menezes
We have postulated a single pole for the self-energy, , looking for the consequences on the one-particle Green function, in the Hubbard model. We find…
