Acoplamento interbanda induzido por hibridizacão a temperatura nula em supercondutores de duas bandas

Abstract

Since its discovery, superconductivity has been an object of increasing interest in the scientific community and the application of its unusual characteristics to the technology of the macroscopic world. For this, the study or behavior of these materials at low temperatures is essential, since recent research points to interesting discoveries, whose limit is the corroborated or the understanding of superconductivity as a whole. Bearing in mind a useful observation about a particularity of two-band superconductors, more specific about the implications for interband coupling, resulting from the application of hybridization on the zero temperature system was studied in the present work. For that, there was a need to calculate the general form or the order parameters that represent the two possible types of comparison, an intrinsic resource and one with mixed characteristics, to later explore graphs ∆ × V and δ × V at zero temperature, which illustrates how these order parameters react to hybridization, in particular or interband coupling in addition to the behavior of the energy bands of the system and comparisons with models previously studied.
