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…
Spectral representation of the shear viscosity for local scalar QFTs at finite temperature
Peter Lowdon, Ralf-Arno Tripolt, Jan M. Pawlowski +1
In local scalar quantum field theories (QFTs) at finite temperature correlation functions are known to satisfy certain non-perturbative constraints, which for two-point functions i…
