Precision many-body theory for the Hubbard model and beyond: the knowns, the known unknowns, and the unknown unknownns

 · Invited

Abstract

This talk will summarize the present status of our knowledge of the equilibrium properties of the two dimensional Hubbard model, including the regimes of magnetism, superconductivity and the pseudogap and the correlation functions relevant for dynamics. Results obtained by different methods will be compared and regimes of relative agreement and of relative uncertainty will be delineated. The relation of the results to data on cold atom systems and copper-oxide high transition temperature superconductors will be discussed and open issues will be highlighted. Brief mention of nonequilibrium physics will be made.

*Many of the results reported here were obtained by the Simons Collaboration on the Many Electron Problem and were supported by the Simons Foundation. Additional support was proviced by the Division of Materials Research of the National Science Foundation under grant DMR 1308236.
