Multi-scattering processes and spectral properties of low-energy QCD
Konrad Kockler, Jan M. Pawlowski, Franz R. Sattler +2
We compute quark and meson spectral functions in low-energy QCD, including all-order scatterings and decays of pions and the scalar -mode. For low energies the gluons decouple a…
FunKit: A computer algebra toolkit for functional approaches
Franz R. Sattler
We introduce FunKit, a Mathematica package for the derivation and tracing of functional equations from arbitrary master equations. FunKit provides an expression vocabulary and a se…
Thermal precondensation in gauge-fermion theories
Álvaro Pastor-Gutiérrez, Jan M. Pawlowski, Franz R. Sattler
Precondensation is a peculiar phenomenon in phase transitions, characterised by the occurrence of a condensate only over a finite range of length scales. It is closely connected to…
Classical equipartition dynamics between axions and non-Abelian gauge fields
Kim V. Berghaus, Adrien Florio, M. Laine +1
Motivated by axion-like inflation and its warm embedding within the Standard Model, we study the early stages of the energy transfer between an axion condensate and an SU(2) gauge…
Inhomogeneous instabilities in high-density QCD
Jan M. Pawlowski, Fabian Rennecke, Franz R. Sattler
QCD at large densities exhibits a moat regime in the scalar-pseudoscalar sector. The resolution of its dynamics is pivotal for the access to the onset of new phases including the p…
DiFfRG: A Discretisation Framework for functional Renormalisation Group flows
Franz R. Sattler, Jan M. Pawlowski
We introduce DiFfRG (Discretisation Framework for functional Renormalisation Group flows), a comprehensive computational C++ framework for solving functional Renormalisation Group…
Towards quantitative precision in functional QCD I
Friederike Ihssen, Jan M. Pawlowski, Franz R. Sattler +1
Functional approaches are the only first principle QCD setup that allow for direct computations at finite density. Predictive power and quantitative reliability of the respective r…
Soft modes in hot QCD matter
Jens Braun, Yong-rui Chen, Wei-jie Fu +9
The chiral crossover of QCD at finite temperature and vanishing baryon density turns into a second order phase transition if lighter than physical quark masses are considered. If t…
