The zoo of states in the 2D Hubbard model — •Robin Scholle, Pietro Bonetti, Demetrio Vilardi, and Walter Metzner — MPI for Solid State Research, Stuttgart, Germany

We use real-space Hartree-Fock theory to unbiasedly construct a phase diagram of the 2D Hubbard model in temperature and doping. We are able to detect various spin- and charge order patterns including Néel, stripe and spiral order. I will give a short summary of the method followed by a presentation of our current results and a possible outlook for further applications.
