Dissipation dynamics of a scalar field
Laura Batini, Eduardo Grossi, Nicolas Wink
We investigate the dissipation rate of a scalar field in the vicinity of the phase transition and the ordered phase, specifically within the universality class of model A. This dis…
Numerical fluid dynamics for FRG flow equations: Zero-dimensional QFTs as numerical test cases. II. Entropy production and irreversibility of RG flows
Adrian Koenigstein, Martin J. Steil, Nicolas Wink +2
We demonstrate that the reformulation of renormalization group (RG) flow equations as non-linear heat equations has severe implications on the understanding of RG flows in general.…
Numerical fluid dynamics for FRG flow equations: Zero-dimensional QFTs as numerical test cases. I. The model
Adrian Koenigstein, Martin J. Steil, Nicolas Wink +4
The functional renormalization group (FRG) approach is a powerful tool for studies of a large variety of systems, ranging from statistical physics over the theory of the strong int…
Resolving phase transitions with Discontinuous Galerkin methods
Eduardo Grossi, Nicolas Wink
We demonstrate the applicability and advantages of Discontinuous Galerkin (DG) schemes in the context of the Functional Renormalization Group (FRG). We investigate the -model…
