Effect of hybridization parity on multiband superconductors properties

We investigated the influence that hybridization parity has on the so-called multiband superconductors, where we proposed a model with two bands [Formula: see text] and [Formula: see text]. Thus, we observe the behavior of intra-band superconductivity, the one whose coupling occurs between carriers that belong to the same band [Formula: see text] or [Formula: see text], and inter-bands, when the coupling occurs between carriers of different bands [Formula: see text] with [Formula: see text] — from graphs of the order parameter as a function of hybridization and the order parameter as a function of temperature, for null temperature in the first case and for finite temperature in the second, as well as intraband phase diagrams. In this sense, the study of the influence that hybridization has on superconductivity is fundamental for understanding unconventional superconductors, such as heavy fermions and high-temperature superconductors.
