Talk

The functional renormalization group (FRG) formulated in real time on the Schwinger-Keldysh closed-time path provides an excellent calculational tool for real-time quantities such as spectral functions and transport coefficients, and in particular for their universal static and dynamic scaling behavior near a critical point. In this talk I will present the novel formulation of FRG flows in...

Talk

I will talk about the reflections of confinement phenomena as seen in the solution for the gluon and the quark propagators in the Minkowski space formalism of QCD gap equations. Further, the solution and its gauge dependence will be shown in the case of walking gauge theory.
