Physics Stack Exchange Questions and Answers
I find particularly interesting the Physics Stack Exchange forum since it allows for the discussion of all kinds of physics questions at a very good level. In fact, one can realize how badly some concepts are understood by trying to answer some of these questions.
Derivation of Expression for Berry curvature in a twolevel system (of particular interest for topological insulators)
ChernSimons term: Integrating out Gapped fermions in 2+1 dimensions coupled to external gauge field
