Query: QCD thermodynamics of effective models with an improved Polyakov-loop
  potential   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-loop potential that can be used in future model studies.
In the present work, we employe this improved potential in a study of a 2+1
flavour Polyakov-quark-meson model and show that the temperature dependence of
the order parameters and thermodynamics is closer to full QCD. We discuss the
results for QCD thermodynamics and outline briefly the dependence of our
results on the critical temperature and the parametrisation of the
Polyakov-loop potential as well as the mass of the sigma-meson.
