Universal behavior of coupled order parameters below three dimensions
Julia Borchardt, Astrid Eichhorn
We explore universal critical behavior in models with two competing order parameters, and an O(N)+O(M) symmetry for dimensions . In d=3, there is always exactly one stabl…

Solving functional flow equations with pseudo-spectral methods
Julia Borchardt, Benjamin Knorr
We apply pseudo-spectral methods to integrate functional flow equations with high accuracy, extending earlier work on functional fixed point equations \cite{Borchardt:2015rxa}. The…

Global flow of the Higgs potential in a Yukawa model
Julia Borchardt, Holger Gies, René Sondenheimer
We study the renormalization flow of the Higgs potential as a function of both field amplitude and energy scale. This overcomes limitations of conventional techniques that rely, e.…
