We study interaction effects in topological insulators with strong spin-orbit coupling. We find that the interplay of nontrivial topology and the Coulomb repulsion induces a novel critical state on the surface of a three dimensional topological insulator. Remarkably, this interaction-induced critical state, characterized by a universal value of electrical conductivity, emerges without any adjustable parameters. Furthermore, we predict a direct quantum-spin-Hall transition in two dimensions that occurs via a similar critical state.
