Non-perturbative renormalization flow in quantum field theory and statistical physics
J Berges, N Tetradis, C Wetterich - Physics Reports, 2002 - Elsevier
We review the use of an exact renormalization group equation in quantum field theory and
statistical physics. It describes the dependence of the free energy on an infrared cutoff for the …

Optimized renormalization group flows
DF Litim - Physical Review D, 2001 - APS
We study the optimization of exact renormalization group (ERG) flows. We explain why the
convergence of approximate solutions towards the physical theory is optimized by …

Chiral symmetry breaking in continuum QCD
M Mitter, JM Pawlowski, N Strodthoff - Physical Review D, 2015 - APS
We present a quantitative analysis of chiral symmetry breaking in two-flavor continuum QCD
in the quenched limit. The theory is set up at perturbative momenta, where asymptotic …

[HTML][HTML] The phase structure of the Polyakov–quark–meson model beyond mean field
TK Herbst, JM Pawlowski, BJ Schaefer - Physics Letters B, 2011 - Elsevier
The Polyakov-extended quark–meson model (PQM) is investigated beyond mean-field. This
represents an important step towards a fully dynamical QCD computation. Both the quantum …

Dark confinement and chiral phase transitions: gravitational waves vs matter representations
A bstract We study the gravitational-wave signal stemming from strongly coupled models
featuring both, dark chiral and confinement phase transitions. We therefore identify strongly …
