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…
Functional flows for complex effective actions
Friederike Ihssen, Jan M. Pawlowski
In the present work we set up a general functional renormalisation group framework for the computation of complex effective actions. For explicit computations we consider both flow…
Renormalised spectral flows
Jens Braun, Yong-rui Chen, Wei-jie Fu +11
We derive renormalised finite functional flow equations for quantum field theories in real and imaginary time that incorporate scale transformations of the renormalisation conditio…
Gluon condensates and effective gluon mass
Jan Horak, Friederike Ihssen, Joannis Papavassiliou +3
Lattice simulations along with studies in continuum QCD indicate that non-perturbative quantum fluctuations lead to an infrared regularisation of the gluon propagator in covariant…
