Gluon-Meson Duality in the Mean Field Approximation
C. Wetterich
In a gauge-fixed language gluon-meson duality can be described as the Higgs mechanism for ``spontaneous symmetry breaking'' of color. We present a mean field computation which sugg…
Time evolution of correlation functions and thermalization
Gian Franco Bonini, Christof Wetterich
We investigate the time evolution of a classical ensemble of isolated periodic chains of O(N)-symmetric anharmonic oscillators. Our method is based on an exact evolution equation f…
Gluon-Meson Duality
Christof Wetterich
The QCD-vacuum is characterized by the Higgs phenomenon for colored scalar fields. In this dual picture the gluons appear as the octet of vector mesons. Also quarks and baryons are…
Flow Equations for Phase Transitions in Statistical Physics and 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…
