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 or intercalated graphite.
