Algebraic-Dynamical Perturbation Theory of Large-$U$ Hubbard Models. Single Particle Spectrum of Antiferromagnetic Mott Insulating States

Wenxin Ding, Rong Yu

In this work, we present an analytical framework for studying antiferromagnetic (AFM) Mott insulating states in the Hubbard model. We first derive an analytical solution for the si…
