The role of fluctuations in the QCD phase diagram — •Naseemuddin Khan¹, Jan Martin Pawlowski¹, Kenji Fukushima², and Nils Strodthoff¹ — ¹Institute of Theoretical Physics Heidelberg — ²Departement of Physics, Tokio University

We construct an effective quark meson diquark model to simulate QCD at low energies. We employ the framework of the functional renormalization group, within which fluctuations of fermions and bosons can be included. We study the behavior of the chiral condensate at various temperatures and chemical potentials as well as the diquark condensate, which arises at higher chemical potentials.
