Fermionic excitations at finite temperature and density
Ralf-Arno Tripolt, Dirk H. Rischke, Lorenz von Smekal +1
We study fermionic excitations in a hot and dense strongly interacting medium consisting of quarks and (pseudo-)scalar mesons. In particular, we use the two-flavor quark-meson mode…

Spectral functions of confined particles
Daniele Binosi, Ralf-Arno Tripolt
We determine the gluon and ghost spectral functions along with the analytic structure of the associated propagators from numerical data describing gauge correlators at space-like m…

Spectral Functions from the Functional Renormalization Group
Jochen Wambach, Christopher Jung, Fabian Rennecke +2
We present results for in-medium spectral functions obtained within the Functional Renormalization Group framework. The analytic continuation from imaginary to real time is perform…
