Query: Faraday rotation in bilayer and trilayer graphene in the quantum Hall
  regime   Optical Hall conductivity, as directly related to Faraday rotation, is
theoretically studied for bilayer and trilayer graphene. In bilayer graphene,
the trigonal warping of the band dispersion greatly affects the resonance
structures in Faraday rotation not only in the low-energy region where small
Dirac cones emerge, but also in the higher-energy parabolic bands as a sequence
of satellite resonances. In ABA-stacked trilayer, the resonance spectrum is a
superposition of effective monolayer and bilayer contributions with band gaps,
while ABC trilayer exhibits a distinct spectrum peculiar to the cubic-dispersed
bands with a strong trigonal warping, where the signals associated with
low-energy Dirac cones should be directly observable owing to a large Lifshitz
transition energy ($\sim 10 meV$).
