Author(s): Shu-Hui Zhang, Wen Yang, and F. M. PeetersMassless Dirac fermions (MDFs) emerge as quasiparticles in various novel materials such as graphene and topological insulators, and they exhibit several intriguing properties, of which Veselago focusing is an outstanding example with a lot of possible applications. However, up to now Veselago focusi…[Phys. Rev. B 97, 205437] Published Tue May 22, 2018
