Dense baryonic matter: constraints from recent neutron star observations
Thomas Hell, Wolfram Weise
Updated constraints from neutron star masses and radii impose stronger restrictions on the equation of state for baryonic matter at high densities and low temperatures. The existen…
Dense nucleonic matter and the renormalization group
Matthias Drews, Thomas Hell, Bertram Klein +1
Fluctuations are included in a chiral nucleon-meson model within the framework of the functional renormalization group. The model, with parameters fitted to reproduce the nuclear l…
Thermodynamic phases and mesonic fluctuations in a chiral nucleon-meson model
Matthias Drews, Thomas Hell, Bertram Klein +1
Studies of the QCD phase diagram must properly include nucleonic degrees of freedom and their thermodynamics in the range of baryon chemical potentials characteristic of nuclear ma…
Impact of vector-current interactions on the QCD phase diagram
Thomas Hell, Kouji Kashiwa, Wolfram Weise
Using a nonlocal version of the Polyakov-loop-extended Nambu--Jona-Lasinio model, we investi- gate effects of a nonderivative vector-current interaction (relating to the quark-numb…
Nonlocal Polyakov-Nambu-Jona-Lasinio model and imaginary chemical potential
Kouji Kashiwa, Thomas Hell, Wolfram Weise
With the aim of setting constraints for the modeling of the QCD phase diagram, the phase structure of the two-flavor Polyakov-loop extended Nambu and Jona-Lasinio (PNJL) model is i…
Extensions and further applications of the nonlocal Polyakov--Nambu--Jona-Lasinio model
Thomas Hell, Kouji Kashiwa, Wolfram Weise
The nonlocal Polyakov-loop-extended Nambu--Jona-Lasinio (PNJL) model is further improved by including momentum-dependent wave-function renormalization in the quark quasiparticle pr…
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…
Thermodynamics of a three-flavor nonlocal Polyakov--Nambu--Jona-Lasinio model
T. Hell, S. Rößner, M. Cristoforetti +1
The present work generalizes a nonlocal version of the Polyakov loop-extended Nambu and Jona-Lasinio (PNJL) model to the case of three active quark flavors, with inclusion of the a…
Monte-Carlo simulations of QCD Thermodynamics in the PNJL model
M. Cristoforetti, T. Hell, W. Weise
We apply a Monte-Carlo method to the two flavor Polyakov loop extended Nambu and Jona-Lasinio (PNJL) model. In such a way we can go beyond mean field calculations introducing fluct…
Dynamics and thermodynamics of a nonlocal Polyakov--Nambu--Jona-Lasinio model with running coupling
T. Hell, S. Roessner, M. Cristoforetti +1
A nonlocal covariant extension of the two-flavor Nambu and Jona-Lasinio (NJL) model is constructed, with built-in constraints from the running coupling of QCD at high-momentum and…
The chiral and deconfinement crossover transitions: PNJL model beyond mean field
Simon Roessner, Thomas Hell, Claudia Ratti +1
The Polyakov loop extended Nambu and Jona-Lasinio model (PNJL model) in a mean field framework shows astonishingly good agreement with lattice QCD calculations which needs to be be…
