Time evolution of correlation functions in Non-equilibrium Field Theories
Luis M. A. Bettencourt, Christof Wetterich
We investigate the non-equilibrium properties of an N-component scalar field theory. The time evolution of the correlation functions for an arbitrary ensemble of initial conditions…
Nonperturbative Flow Equations, Low-Energy QCD and the Chiral Phase Transition
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…
Effective Quark Interactions and QCD-Propagators
Bastian Bergerhoff, Christof Wetterich
We compute the momentum dependence of the effective four quark interaction in QCD after integrating out the gluons. Our method is based on a truncation of exact renormalization gro…
Quantum Dynamics in Classical Time Evolution of Correlation Functions
Christof Wetterich
The time-dependence of correlation functions under the influence of classical equations of motion is described by an exact evolution equation. For conservative systems thermodynami…
