Curvature of the QCD phase transition line in a finite volume
Bertram Klein, Jens Braun, Bernd-Jochen Schaefer
The curvature which characterizes the QCD phase transition at finite temperature and small values of the chemical potential is accessible to lattice simulations. The results for th…
Second-order and Fluctuation-induced First-order Phase Transitions with Functional Renormalization Group Equations
Kenji Fukushima, Kazuhiko Kamikado, Bertram Klein
We investigate phase transitions in scalar field theories using the functional renormalization group (RG) equation. We analyze a system with symmetry, in which th…
On the scaling behavior of the chiral phase transition in QCD in finite and infinite volume
Jens Braun, Bertram Klein, Piotr Piasecki
We study the scaling behavior of the two-flavor chiral phase transition using an effective quark-meson model. We investigate the transition between infinite-volume and finite-volum…
Thermodynamics and quark susceptibilities: a Monte-Carlo approach to the PNJL model
M. Cristoforetti, T. Hell, B. Klein +1
The Monte-Carlo method is applied to the Polyakov-loop extended Nambu--Jona-Lasinio (PNJL) model. This leads beyond the saddle-point approximation in a mean-field calculation and i…
