Time Evolution of Non-Equilibrium Effective Action
Christof Wetterich
The time evolution of correlation functions in statistical systems is described by an exact functional differential equation for the corresponding generating functionals. This allo…
Electroweak Phase Transition in the Early Universe ?
Bastian Bergerhoff, Christof Wetterich
Existence and properties of the electroweak phase transition in the early universe depend strongly on the mass of the Higgs scalar M_H. There is presumably no true symmetry restora…
Nonperturbative Flow Equations and Low--Energy QCD
D. -U. Jungnickel, C. Wetterich
We review the formalism of the effective average action in quantum field theory which corresponds to a coarse grained free energy in statistical mechanics. The associated exact ren…
Equation of state and coarse grained free energy for matrix models
J. Berges, C. Wetterich
We investigate phase transitions in three dimensional scalar matrix models, with special emphasis on complex matrices. The universal equation of state for weak first o…
Quantum Liouville Field Theory as Solution of a Flow Equation
M. Reuter, C. Wetterich
A general framework for the Weyl invariant quantization of Liouville field theory by means of an exact renormalization group equation is proposed. This flow equation describes the…
Integrating out Gluons in Flow Equations
Christof Wetterich
We present an exact nonperturbative flow equation for the average action for quarks which incorporates the effects of gluon fluctuations. With suitable truncations this allows one…
