Description
Using the recently introduced combination of the fRG with the DMFT, coined DMF2RG, we compute the frequency- and momentum-dependent self-energy of the two-dimensional Hubbard model at strong coupling. For this, we extend the single-boson exchange formulation of the fRG for the computation of the self-energy flow with the Schwinger-Dyson equation. This has shown to be essential to capture the pseudogap opening in the weak-coupling regime. We discuss the structure of the flow equations and present numerical results for the self-energy.
