The electromagnetic response of bilayer graphene in a magnetic field isstudied in comparison with that of monolayer graphene. Both types of grapheneturn out to be qualitatively quite similar in dielectric and screeningcharacteristics, especially those deriving from vacuum fluctuations, but theeffect is generally much more sizable for bilayers. The presence of thezero-(energy-)mode Landau levels is a feature specific to graphene. Inbilayers, unlike in monolayers, the effect of the zero-mode levels becomesvisible and even dominant in density response as an externally-controllableband gap develops. It is pointed out that the splitting of nearly-degeneratepseudo-zero-mode levels at each valley, specific to bilayer graphene, iscontrolled by an applied inplane electric field or by an injected current. Inaddition, a low-energy effective gauge theory of bilayer graphene isconstructed.
