On the contribution of plasminos to the shear viscosity of a hot and dense Yukawa-Fermi gas

Abstract

Using the standard Green-Kubo formalism, we determine the shear viscosity $\eta$ of a hot and dense Yukawa-Fermi gas. In particular, we study the effect of particle and plasmino excitations on thermal properties of the fermionic part of the shear viscosity, and explore the effects of thermal corrections to particle masses on bosonic and fermionic shear viscosities, ${\eta }_b$ and ${\eta }_f$. It turns out that the effects of plasminos on ${\eta }_f$ become negligible with increasing (decreasing) temperature (chemical potential).
