Abstract: A number of quantities in quantum many-body systems show
remarkable universality properties, in the sense of exact independence
from microscopic details. I will present some rigorous result
establishing universality in presence of many body interaction in
Graphene and in Topological Insulators, both for the bulk and edge
transport. The proof uses Renormalization Group methods and a
combination of lattice and emerging Ward Identities.
