abstract = {Using the recently introduced multiloop extension of the
functional renormalization group, we compute the frequency-
and momentum-dependent self-energy of the two-dimensional
Hubbard model at half filling and weak coupling. We show
that, in the truncated-unity approach for the vertex, it is
essential to adopt the Schwinger-Dyson form of the
self-energy flow equation in order to capture the pseudogap
opening. We provide an analytic understanding of the key
role played by the flow scheme in correctly accounting for
the impact of the antiferromagnetic fluctuations. For the
resulting pseudogap, we present a detailed numerical
analysis of its evolution with temperature, interaction
strength, and loop order.},
