Bound States and Supercriticality in Graphene-Based Topological Insulators
arXiv:1301.2833 · 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
