Bound States and Supercriticality in Graphene-Based Topological Insulators

Bound States and Supercriticality in Graphene-Based Topological Insulators

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.
