Resumen:
We study the Euclidean effective action per unit area and thecharge density for a Dirac field in a two--dimensional spatialregion, in the presence of a uniform magnetic field perpendicularto the 2D--plane, at finite temperature and density. In the limitof zero temperature we reproduce, after performing an adequateLorentz boost, the Hall conductivity measured for different kindsof graphene samples, depending upon the phase choice in thefermionic determinant.
