Self-consistent model spectral functions from analytically continued FRG flows
Christopher Jung, Jan-Hendrik Otto, Ralf-Arno Tripolt +1
In this paper we explore practicable ways for self-consistent calculations of spectral functions from analytically continued functional renormalization group (aFRG) flow equations.…
Vector and Axial-Vector Mesons in Nuclear Matter
Ralf-Arno Tripolt, Christopher Jung, Lorenz von Smekal +1
As a first step towards a realistic phenomenological description of vector and axial-vector mesons in nuclear matter, we calculate the spectral functions of the and the m…
Fluctuating vector mesons in analytically continued FRG flow equations
Christopher Jung, Lorenz von Smekal
In this work we study contributions due to vector and axial-vector meson fluctuations to their in-medium spectral functions in an effective low-energy theory inspired by the gauged…
In-medium spectral functions and dilepton rates with the Functional Renormalization Group
Ralf-Arno Tripolt, Christopher Jung, Naoto Tanji +2
We present recent results on in-medium spectral functions of vector and axial-vector mesons, the electromagnetic (EM) spectral function and dilepton rates using the Functional Reno…
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…
In-Medium Spectral Functions of Vector- and Axial-Vector Mesons from the Functional Renormalization Group
Christopher Jung, Fabian Rennecke, Ralf-Arno Tripolt +2
In this work we present first results on vector and axial-vector meson spectral functions as obtained by applying the non-perturbative functional renormalization group approach to…
