Abstract
We study the coherent dynamics of Dirac fermions on the surface of topological
insulators in one and two space dimensions. Our finite difference scheme can han-
dle space­ and time­dependent mass and potential terms and is complemented by
newly­developed transparent boundary conditions. Dirac fermions show interesting
dynamical behavior based on effects, such as negative refraction and therefore `su-
