Research Interests
Franz Sattler is a postdoctoral researcher in the $\left\lvert\chi\right\rangle$real (Quantum Information and Real-time evolution in QFT) Emmy Noether research group at Bielefeld University.
Franz’s research on the phase diagram of Quantum Chromodynamics (QCD) utilizes the functional renormalization group (fRG) to explore the high-density regime, which is crucial for upcoming collider experiments such as CBM at FAIR, HADES at GSI, and J-PARC-HI in Japan. Franz is a member of the fQCD-Collaboration.
Franz’s broader research interests include:
- Real-time lattice simulations for early-universe cosmology & ultracold atoms.
- Simulation of real-time quantum systems using tensor networks.
- QCD phase diagram and critical endpoint at high densities.
- Color superconductivity and neutron star physics.
- Systematics of functional Renormalization Group approaches in QFT.

Software Development
Lead developer of DiFfRG (Discretisation Framework for functional Renormalization Group flows), a general-purpose open-source framework in C++/Mathematica/Python for fRG calculations that is used in the fQCD collaboration between Heidelberg, Darmstadt, Gießen, Beijing, and Dalian. The framework supports automatic diagram derivation and numerical evaluation of flows as PDEs for complex multi-sector systems.
Lead developer of TensorBases, a Matehematica package for the derivation, transformation of tensorial interaction bases in general QFTs, together with automatic definitions of projection operators and vertices.
