ABSTRACT
When bilayer graphene is gated with a kink potential, pair particle localization occurs at the kink where a particle (electron) and its chiral partner (hole) are held in balance by electrostatic coupling. Zero-energy states (zero modes) are always present in pairs and occur at the same point in the dispersion graph, regardless of kink strength. The robust and binary nature of the kink-induced modes, which are topologically protected against disorder, and the ease with which a kink is created suggest applications in switching devices or information storage.

    We study the coupling between a relavistic pair plasma and a nonlinear, superluminal, transverse electromagnetic (TEM) wave, both in the free-streaming case and in the case where the plasma encounters a shock produced by a confining medium. For the free-streaming case, we verify an analytically...
