Condensed Matter Seminar in Physics 110 PAN
Speaker: Emanuel Gull, University of Michigan
Subject: Numerical experiment on the Hubbard model

The Hubbard model is one of the fundamental models of correlated electron physics. In two dimensions it exhibits various superconducting, Mott insulating, magnetically ordered, pseudogapped, and metallic phases. On a square lattice and for repulsive interactions comparable to the bandwidth, the model is believed to capture much of the low-energy physics of the cuprate high-temperature superconductors, while in three dimensions it can be realized experimentally in ultracold atomic gases. In this talk I will show results from `numerical experiment’ on this model and compare them to experimentally obtained response functions and theoretical calculations, illustrating how simulations can be used to further our understanding of correlated electron systems.
