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…
Quark and Nuclear Matter in the Linear Chiral Meson Model
J. Berges, D. -U. Jungnickel, C. Wetterich
We present an analytical description of the phase transitions from a nucleon gas to nuclear matter and from nuclear matter to quark matter within the same model. The equation of st…
The chiral phase transition from the exact RG
D. -U. Jungnickel
A brief introduction is given to the concept of the effective average action. Its dependence on the averaging or coarse graining scale is governed by an exact RG equation for which…
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…
Two flavor chiral phase transition from nonperturbative flow equations
J. Berges, D. -U. Jungnickel, C. Wetterich
We employ nonperturbative flow equations to compute the equation of state for two flavor QCD within an effective quark meson model. This yields the temperature and quark mass depen…
The Linear Meson Model and Chiral Perturbation Theory
Dirk-U. Jungnickel, C. Wetterich
We compare the linear meson model and chiral perturbation theory in next to leading order in the quark mass expansion. In particular, we compute the couplings L_4--L_8 of chiral pe…
