Magneto-absorption spectra of Bernal graphite

With the availability of Landau wave functions in real space, we investigate the magneto-optical spectra of ordinary bulk graphite within a tight-binding model. The interlayer interactions significantly affect the structure, frequency and intensity of absorption peaks, as well as their field evolution and the double-peak absorptions. Those unique features of the absorption constitute important characterization of graphite and serve to differentiate the bulk spectra from those of true monolayer and bilayer graphenes.
