Finite temperature spectral functions in the O(N)-model
Jan M. Pawlowski, Nils Strodthoff, Nicolas Wink
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 nu…

Self-consistent Spectral Functions in the Model from the FRG
Nils Strodthoff
We present the first self-consistent direct calculation of a spectral function in the framework of the Functional Renormalization Group. The study is carried out in the relativisti…
