Flow Equations and the Chiral Phase Transition
B. -J. Schaefer, O. Bohr, J. Wambach
Flow equations for an O(N)-symmetric effective potential are discussed and solved for the finite temperature case. The model is investigated at the critical point and critical expo…

Nonperturbative Flow Equations with Heat-Kernel Methods at finite Temperature
B. -J. Schaefer, H. J. Pirner
We derive nonperturbative flow equations within an effective constituent quark model for two quark flavors. Heat-kernel methods are employed for a renormalization group improved ef…
