Abstract
We present divERGe, an open source, high-performance C/C++/Python library for functional renormalization group (FRG) calculations on lattice fermions.The versatile model interface is tailored to real materials applications and seamlessly integrates with existing, standard tools from the ab-initio community.The code fully supports multi-site, multi-orbital, and non-SU(2) models in all of the three included FRG variants: TU 2 FRG, N-patch FRG, and grid FRG.With this, the divERGe library paves the way for widespread application of FRG as a tool in the study of competing orders in quantum materials.
