• "Polarization-sensitive absorption of THz radiation by interacting electrons in chirally stacked multilayer graphene", Trushin, Schliemann, 2012

  Publication

  We show that the opacity of a clean multilayer graphene flake depends on the helicity of the circular polarized electromagnetic radiation. The effect...
