If you have a question about this talk, please contact Mustapha Amrani. Spectral Theory of Relativistic Operators In this talk I will discuss the Hartree-Fock approximation of graphene in infinite volume, with instantaneous Coulomb interactions. First I will explain how to construct the translation-invariant ground state. Due to the exchange term, the resulting effective Fermi velocity is logarithmically divergent at zero momentum. Then I will discuss the existence of ground states in the presence of local defects and some properties of the associated nonlinear response. Joint work with C. Hainzl and C. Sparber.
