Query: SU(3) Polyakov linear-sigma model: bulk and shear viscosity of QCD
  matter in finite magnetic field   Due to off-center relativistic motion of the charged spectators and the local
momentum-imbalance of the participants, a short-lived huge magnetic field is
likely generated, especially in relativistic heavy-ion collisions. In
determining the temperature dependence of bulk and shear viscosities of the QCD
matter in vanishing and finite magnetic field, we utilize mean field
approximation to the SU($3$) Polyakov linear-sigma model (PLSM). We compare
between the results from two different approaches; Green-Kubo correlation and
Boltzmann master equation with Chapman-Enskog expansion. We find that both
approaches have almost identical results, especially in the hadron phase. In
the temperature dependence of bulk and shear viscosities relative to thermal
entropy at the critical temperature, there is a rapid decrease in the chiral
phase-transition and in the critical temperature with increasing magnetic
field. As the magnetic field strength increases, a peak appears at the critical
temperature ($T_c$). This can be understood from the small drop on the thermal
entropy at $T_c$, which can be interpreted due to instability in the
hydrodynamic flow of the quark-gluon plasma and soft statistical hadronization.
It is obvious that, increasing magnetic field accelerates the transition from
hadron to QGP phases (inverse catalysis), i.e., taking place at lower
temperatures.
