Universality in graphene and Weyl semimetals

There is an increasing interest in fermionic systems in two or three dimensions whose Fermi surface is point-like, like Graphene or Weyl semimetals. Their properties in the thermodynamic limit can be rigorously investigated for interactions which are short ranged and not too strong, and certain remarkable universality properties can be established, by combining bounds on the large distance decay of correlations with Ward Identities.
