The Hubbard model: insights from a computational proxy
The Hubbard model is to interacting quantum electronic systems as the Ising model is to classical statistical mechanics. Its apparent simplicity and widely believed relevance to the high-temperature superconductors have motivated an enormous amount of work over the past six decades. Still, much remains unknown. I will describe what is known with theoretical confidence about the phase diagram of the Hubbard model, both analytically and numerically. I will then present results from a determinant quantum Monte Carlo study of a related bilayer system that is free of the sign problem, and discuss the extent to which it may serve as a computational proxy to the Hubbard model.
