Magneto-electronic properties of rhombohedral trilayer graphene: Peierls tight-binding model

 RHtriangle Three groups of Landau levels of ABC-stacked trilayer graphene are obtained.  RHtriangle They are strongly affected by the stacking configuration and interlayer interactions.  RHtriangle Based on the wave function characteristics, an effective quantum number is defined.  RHtriangle Three sets of effective quantum numbers are used to index the Landau levels.  RHtriangle These quantum numbers are useful for defining the optical selection rules.
