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…
Optimization and Stabilization of Functional Renormalization Group Flows
Niklas Zorbach, Jonas Stoll, Jens Braun
We revisit optimization of functional renormalization group flows by analyzing regularized loop integrals. This leads us to a principle, the Principle of Strongest Singularity, and…
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…
Lattice investigation of an inhomogeneous phase of the 2+1-dimensional Gross-Neveu model in the limit of infinitely many flavors
Marc Winstel, Jonas Stoll, Marc Wagner
We investigate the phase structure of the 2+1-dimensional Gross-Neveu model in the large-Nf limit, where Nf denotes the number of fermion flavors. We discuss two different fermion…
