On the efficient computation of high-order derivatives for implicitly defined functions
Mathias Wagner, Andrea Walther, Bernd-Jochen Schaefer
Scientific studies often require the precise calculation of derivatives. In many cases an analytical calculation is not feasible and one resorts to evaluating derivatives numerical…
QCD Thermodynamics: Confronting the Polyakov-Quark-Meson Model with Lattice QCD
Jochen Wambach, Bernd-Jochen Schaefer, Mathias Wagner
NJL-type effective models represent a low-energy realization of QCD and incorporate pertinent aspects such as chiral symmetry and its spontaneous breaking, the center symmetry in t…
Thermodynamics of (2+1)-flavor QCD: Confronting Models with Lattice Studies
Bernd-Jochen Schaefer, Mathias Wagner, Jochen Wambach
The Polyakov-quark-meson (PQM) model, which combines chiral as well as deconfinement aspects of strongly interacting matter is introduced for three light quark flavors. An analysis…
QCD thermodynamics with effective models
Bernd-Jochen Schaefer, Mathias Wagner, Jochen Wambach
In this talk we extend the Polyakov-quark-meson model to N_f=2+1 quark flavors and study its bulk thermodynamics at finite temperatures in mean-field approximation. Three different…
