Analysis of regulator and cutoff artifacts in the phase diagram of the quark-meson model
Jonas Stoll, Niklas Zorbach, Lutz Kiefer +3
We study regulator and cutoff artifacts in the quark-meson model at finite temperature and quark chemical potential within the functional renormalization-group approach using the l…
Nonperturbative fluctuation effects of charged bosonic fields: A quark-diquark model study at nonzero density
Jonas Stoll, Niklas Zorbach, Jens Braun
We study the renormalization group flow of the scale-dependent effective potential of a quark-diquark model with full field dependence at nonzero chemical potential. This includes…
Lattice Monte Carlo meets lattice functional Renormalization Group: A quantitative comparison
Niklas Zorbach, Jan Philipp Klinger, Owe Philipsen +1
Lattice Monte Carlo (MC) simulations and the functional Renormalization Group (RG) are powerful approaches that allow for quantitative studies of non-perturbative phenomena such as…
Functional Renormalization Group meets Computational Fluid Dynamics: RG flows in a multi-dimensional field space
Niklas Zorbach, Adrian Koenigstein, Jens Braun
Within the Functional Renormalisation Group (FRG) approach, we present a fluid-dynamical approach to solving flow equations for models living in a multi-dimensional field space. To…
Solving the Lindblad equation with methods from computational fluid dynamics
Jan Rais, Adrian Koenigstein, Niklas Zorbach +1
Liouvillian dynamics describes the evolution of a density operator in closed quantum systems. One extension towards open quantum systems is provided by the Lindblad equation. It is…
Bosonic fluctuations in the -dimensional Gross-Neveu(-Yukawa) model at varying and and finite
Jonas Stoll, Niklas Zorbach, Adrian Koenigstein +2
Using analogies between flow equations from the Functional Renormalization Group and flow equations from (numerical) fluid dynamics we investigate the effects of bosonic fluctuatio…
