QCD thermodynamics of effective models with an improved Polyakov-loop potential
Rainer Stiele, Lisa M. Haas, Jens Braun +2
We analyse the role of the quark backreaction on the gauge-field dynamics and its impact on the Polyakov-loop potential. Based on our analysis we construct an improved Polyakov-loo…
Improved Polyakov-loop potential for effective models from functional calculations
Lisa M. Haas, Rainer Stiele, Jens Braun +2
We investigate the quark backreaction on the Polyakov loop and its impact on the thermodynamics of quantum chromodynamics. The dynamics of the gluons generating the Polyakov-loop p…
Phase diagram and surface tension in the three-flavor Polyakov-quark-meson model
Bruno W. Mintz, Rudnei O. Ramos, Juergen Schaffner-Bielich +1
We obtain the in-medium effective potential of the three-flavor Polyakov-Quark-Meson model as a real function of real variables in the Polyakov loop variable, to allow for the stud…
Self-interacting Dark Matter Energy Density
Rainer Stiele, Tillmann Boeckel, Jurgen Schaffner-Bielich
We investigate cosmological implications of an energy density contribution arising by elastic dark matter self-interactions. Its scaling behaviour shows that it can be the dominant…
