Pseudogap opening in the two-dimensional Hubbard model: A functional renormalization group analysis
Cornelia Hille, Daniel Rohe, Carsten Honerkamp, Sabine Andergassen
Abstract
The authors propose a Schwinger-Dyson form for the renormalization group flow of the self-energy, that captures the pseudogap opening in the two-dimensional Hubbard model at half filling as it accounts for the impact of the antiferromagnetic fluctuations.
