We directly calculate spectral functions in the O(N)-model at finite temperature within the framework of the Functional Renormalization group. Special emphasis is put on a fully numerical framework involving four-dimensional regulators preserving Euclidean O(4) and Minkowski Lorentz invariance, an important prerequisite for future applications. Pion and sigma meson spectral functions are calculated for a wide range of temperatures across the phase transition illustrating the applicability of the general framework for finite temperature applications. In addition, various aspects concerning the interplay between the Euclidean and real time two-point function are discussed.

The QCD moat regime and its real-time properties
A first computation of the pion spectral function in the QCD moat regime reveals a quasiparticle peak at nonzero spacelike momentum, the moaton, and indicates no instability toward inhomogeneous chiral condensation fo...

The causal structure of the quark propagator
In a spectral DSE computation, the quark propagator develops complex-conjugate poles when the classical quark-gluon vertex strength exceeds a critical value, while the full QCD strength is predicted to stay below that value.

Phase structure of quark matter and in-medium properties of mesons from Callan-Symanzik flows
A symmetry-restored Callan-Symanzik functional RG produces a physical phase diagram and meson spectral functions for the quark-meson model, where the unconstrained scheme fails.

Critical scaling for spectral functions
A spectral renormalisation group computation extracts the anomalous dimension eta ~ 0.1 for 2+1-dimensional phi^4 theory in the scaling regime, within a truncated approximation.
