Renormalization flow from UV to IR degrees of freedom
Holger Gies, Christof Wetterich
Within the framework of exact renormalization group flow equations, a scale-dependent transformation of the field variables provides for a continuous translation of UV to IR degree…
The Influence of Quintessence on the Separation of CMB Peaks
Michael Doran, Matthew Lilley, Jan Schwindt +1
A hypothetical dark energy component may have an equation of state that is different from a cosmological constant and possibly even changing in time. The spacing of the cosmic micr…
Quantum correlations from incomplete classical statistics
C. Wetterich
We formulate incomplete classical statistics for situations where the knowledge about the probability distribution outside a local region is limited. The information needed to comp…
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…
Time evolution of correlation functions for classical and quantum anharmonic oscillators
Luis M. A. Bettencourt, C. Wetterich
The time evolution of the correlation functions of an ensemble of anharmonic N-component oscillators with O(N) symmetry is described by a flow equation, exact up to corrections of…
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…
