This article is devoted to discussing the inter-relation between the political consciousness of the peoples and the construction of the great Latin American and Caribbean Homeland, which is expressed through the class struggle, when there is awarenes

This work extends the calculations performed by G. Litak, T. Ord, K. Rago, and A. Vargunin, Physica C 483, 30 (2012), by including second nearest neighbors in an attractive two-orbital Hubbard model. We assumed that both the intra-orbital (Ui, i, wit

A good description of the electronic structure of BiS2-based superconductors is essential to understand their phase diagram, normal state and superconducting properties. To describe the first reports of normal state electronic structure features from

Using a second-order perturbative Green's functions approach we determined the normal state single-particle spectral function $A(\vec{k},\omega)$ employing a minimal effective model for iron-based superconductors. The microscopic model, used before t

Following a two-pole approximation for strong correlations in the presence of superconductivity, we investigated the interplay between local repulsion and superconductivity, mainly on T c , which is the superconducting critical temperature. In additi

We studied the possible superconducting state in an electronic itinerant ferromagnetic system characterized by a density of states that presents a moderately strong peak that is controlled by a specific parameter a and is positioned near the band edg

A two-band and quartic interaction order Ginzburg–Landau model in the presence of a single vortex is studied in this work. Interactions of second (quadratic, with coupling parameter [Formula: see text]) and fourth (quartic, with coupling parameter

A minimal two-band model to describe superconducting Fe-pnictide materials is considered. It is assumed that the electronic structure of these materials may be modeled in terms of two tight-binding bands, whereas the pairing mechanism is driven by an

We consider as a minimal model for superconductivity in (AlMg)B2 a two-band superconductor, having an anisotropic electronic structure described by two tight binding bands, considering a pairing scenario driven by an attractive interaction in which t
