Physics-informed gauge theories
Friederike Ihssen, Jan M. Pawlowski
We use the physics-informed renormalisation group (PIRG) for the construction of gauge invariant renormalisation group flows. The respective effective action is a sum of a gauge in…
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…
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…
Scalar spectral functions from the spectral fRG
Jan Horak, Friederike Ihssen, Jan M. Pawlowski +2
We compute non-perturbative spectral functions in a scalar -theory in three spacetime dimensions via the spectral functional renormalisation group. This approach allows for th…
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…
