Relativistic Model of two-band Superconductivity in (2+1)-dimension

Abstract

We investigate the relativistic model of superconductivity in (2+1)-dimension. We employ the massless Gross-Neveu model at finite temperature and density, to study the superconductivity and superconducting instability. Our investigation is related to the superconductivity in (2+1)-dimensional two-band systems like $\mathrm{Mg}{\mathrm{B}}_2$ or intercalated graphite.
