The ground state construction of the two-dimensional Hubbard model on the honeycomb lattice
Abstract: In these lectures I consider the half-filled two-dimensional (2D) Hubbard model on the honeycomb lattice and I review the rigorous construction of its ground state properties by making use of constructive fermionic Renormalization Group methods. Lecture notes of a mini-course delivered at the Les Houches summer school 2010 "Quantum Theory: from small to large scales".
Keywords: Hubbard model, two-dimensional inetracting Fermi systems, graphene, renormalization group
