Functional Renormalization Group meets Computational Fluid Dynamics: RG flows in a multi-dimensional field space
Niklas Zorbach, Adrian Koenigstein, Jens Braun
Within the Functional Renormalisation Group (FRG) approach, we present a fluid-dynamical approach to solving flow equations for models living in a multi-dimensional field space. To…

Optimization and Stabilization of Functional Renormalization Group Flows
Niklas Zorbach, Jonas Stoll, Jens Braun
We revisit optimization of functional renormalization group flows by analyzing regularized loop integrals. This leads us to a principle, the Principle of Strongest Singularity, and…
