Relativistic Model for two-band Superconductivity
arXiv:cond-mat/0306472
Abstract
To understand the superconductivity in MgB2, several two-band models of superconductivity were proposed. In this paper, by using the relativistic fermion model, we clearize the effect of the lower band in the superconductivity.
