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…
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…
