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…
