We investigate the structure of the electromagnetic current density for the pseudorelativistic massless spinor effective model for graphene. It is shown that the pseudorelativistic planar massless Dirac theory in the presence of a constant homogeneous electric field actually leads to the recently measured value for the minimum quantum conductivity.

Abstract
We investigate the structure of the electromagnetic current density for the pseudorelativistic massless spinor effective model for graphene. It is shown that the pseudorelativistic planar massless Dirac theory in the presence of a constant homogeneous electric field actually leads to the recently measured value for the minimum quantum conductivity.File in questo prodotto:
