A consistent nonperturbative approach to thermal damping-rates
Bastian Bergerhoff, Juergen Reingruber
We propose a nonperturbative scheme for the calculation of thermal damping-rates using exact renormalization group (RG)-equations. Special emphasis is put on the thermal RG where f…
The Thermal Renormalization Group for Fermions, Universality, and the Chiral Phase-Transition
Bastian Bergerhoff, Johannes Manus, Juergen Reingruber
We formulate the thermal renormalization group, an implementation of the Wilsonian RG in the real-time (CTP) formulation of finite temperature field theory, for fermionic fields. U…
Dynamics of Metastable Vacua in the Early Universe
Bastian Bergerhoff, Manfred Lindner, Manfred Weiser
We study the question whether a possible metastable vacuum state is actually populated in a phase transition in the early universe, as is usually assumed in the discussion of vacuu…
Thermal Renormalization Group-Equations and the Phase-Transition of Scalar O(N)-Theories
Bastian Bergerhoff, Juergen Reingruber
We discuss the formulation of "thermal renormalization group-equations" and their application to the finite temperature phase-transition of scalar O(N)-theories. Thermal renormaliz…
Critical Behavior of phi^4-Theory from the Thermal Renormalization Group
Bastian Bergerhoff
We discuss the universal critical behavior of a selfinteracting scalar field theory at finite temperature as obtained from approximate solutions to nonperturbative renormalization…
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…
