Finite-Temperature Spectral Functions from the Functional Renormalization Group
Ralf-Arno Tripolt, Nils Strodthoff, Lorenz von Smekal +1
We present a method to obtain spectral functions at finite temperature from the Functional Renormalization Group. Our method is based on a thermodynamically consistent truncation o…
Spectral Functions for the Quark-Meson Model Phase Diagram from the Functional Renormalization Group
Ralf-Arno Tripolt, Nils Strodthoff, Lorenz von Smekal +1
We present a method to obtain spectral functions at finite temperature and density from the Functional Renormalization Group. Our method is based on a thermodynamically consistent…
Dyson-Schwinger study of chiral density waves in QCD
Daniel Müller, Michael Buballa, Jochen Wambach
The formation of inhomogeneous chiral condensates in QCD matter at nonzero density and temperature is investigated for the first time with Dyson-Schwinger equations. We consider tw…
Neutron Star Matter
Jochen Wambach
In this presentation I discuss two aspects of the neutron-matter equation of state. One relates to the symmetry energy of nuclear matter and empirical constraints on its slope para…
Real-Time Correlation Functions in the O(N) Model from the Functional Renormalization Group
Kazuhiko Kamikado, Nils Strodthoff, Lorenz von Smekal +1
In the framework of the functional renormalization group (FRG) we present a simple truncation scheme for the computation of real-time mesonic n-point functions, consistent with the…
