Bound States and Supercriticality in Graphene-Based Topological Insulators

Kloepfer, D., De Martino, A. & Egger, R. (2013). Bound States and Supercriticality in Graphene-Based Topological Insulators. Crystals, 3(1), pp. 14-27. doi: 10.3390/cryst3010014

Abstract

We study the bound state spectrum and the conditions for entering a supercritical regime in graphene with strong intrinsic and Rashba spin-orbit interactions within the topological insulator phase. Explicit results are provided for a disk-shaped potential well and for the Coulomb center problem.
