Small shear viscosity in the semiquark gluon plasma
Small shear viscosity in the semiquark gluon plasma
At nonzero temperature in QCD, about the deconfining phase transition there is a semiquark gluon plasma (semi-QGP), where the expectation value of the (renormalized) Polyakov loop is less than one. This can be modeled by a semiclassical expansion about a constant field for the vector potential, ${A}_{0}$, which is diagonal …
