The ground state construction of the two-dimensional Hubbard model on the honeycomb lattice
arXiv:1102.3881
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.
