Description:
Author(s): Thomas Mertz, Karim Zantout, and Roser Valentí We introduce the concept of self-energy dispersion as an error bound on local theories and apply it to the two-dimensional Hubbard model on the square lattice at half filling. Since the self-energy has no single-particle analog and is not directly measurable in experiments, its general behavior as a... [Phys. Rev. B 98, 235105] Published Mon Dec 03, 2018
