Description
The DMF2RG has been introduced to overcome the weak-coupling limitation of the fRG. This approach builds on the idea to exploit the dynamical mean-field theory (DMFT) as starting point for the flow, thus capturing local non-perturbative correlations via DMFT together with perturbative nonlocal correlations generated during the flow. We discuss how the DMF2RG can be extended to describe nonperturbative nonlocal correlations, by using cluster DMFT or cellular DMFT as starting point of the flow.
