Semiclassical approach to 2d impurity bound states in Dirac systems
Kun W. Kim, T. Pereg-Barnea, G. Refael
The goal of this paper is to provide an intuitive and useful tool for analyzing the impurity bound state problem. We develop a semiclassical approach and apply it to an impurity in…
A non-perturbative expression for the transmission through a leaky chiral edge mode
Kun W. Kim, Israel Klich, Gil Refael
Chiral edge modes of topological insulators and Hall states exhibit non-trivial behavior of conductance in the presence of impurities or additional channels. We will present a simp…
Transport through a disordered topological-metal strip
Alexandra Junck, Kun W. Kim, Doron L. Bergman +2
Features of a topological phase, and edge states in particular, may be obscured by overlapping in energy with a trivial conduction band. The topological nature of such a conductor,…
