Abstract Details: I discuss how Quantum Monte Carlo methods developed for studies of the electronic structure of graphene can be applied to carbon nanotubes, and show first results for the interaction-induced energy gap. I also review previous Monte Carlo results for the critical coupling of the semimetal-insulator transition in graphene. I also discuss how our results for carbon nanotubes could be used to constrain the strength and form of the electron-electron interaction in graphene.
