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…
CosmoLattice 2.0
Jorge Baeza-Ballesteros, Daniel G. Figueroa, Adrien Florio +4
This paper introduces , a major upgrade that substantially broadens the physical scope and computational capabilities of the code…
TempLat: a versatile C++ engine for lattice field theories
Adrien Florio, Franz R. Sattler
We present TempLat, a C++ framework for lattice field theory simulations in arbitrary dimensions. Its symbolic language, built on expression templates, translates mathematical expr…
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…
Juggling with Tensor Bases in Functional Approaches
Jens Braun, Andreas Geißel, Jan M. Pawlowski +2
Systematic expansion schemes in functional approaches require the inclusion of higher order vertices. These vertices are expanded in independent tensor bases with a rapidly increas…
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…
Towards quantitative precision for QCD at large densities
Friederike Ihssen, Jan M. Pawlowski, Franz R. Sattler +1
QCD at large density reveals a rich phase structure, ranging from a potential critical end point and inhomogeneous phases or moat regimes to color superconducting ones with competi…
Numerical RG-time integration of the effective potential: Analysis and Benchmark
Friederike Ihssen, Franz R. Sattler, Nicolas Wink
We investigate the RG-time integration of the effective potential in the functional renormalization group in the presence of spontaneous symmetry breaking and its subsequent convex…
Local Discontinuous Galerkin for the Functional Renormalisation Group
Friederike Ihssen, Jan M. Pawlowski, Franz R. Sattler +1
We apply the Local Discontinuous Galerkin discretisation to flow equations of the O(N)-model in the Local Potential Approximation. The improved stability is directly observed by so…
