Query: Transport properties of AB stacked (Bernal) bilayer graphene on and
  without substrate within 2- and 4-band approximations   We present the results of the calculations of longitudinal and Hall
conductivities of AB-stacked bilayer graphene as a function of frequency,
finite chemical potential, temperature both with and without magnetic fields on
a base of 2- and 4-band effective models. The limited cases of the
conductivities for direct current are derived. The relations being important
for optoelectronic among Hall conductivities and Faraday, Kerr angles in the
AB-bilayers samples in the electric and magnetic fields when the radiation
passes across bilayer sheets on different kinds a substrate are obtained.
