Effects of magnetic field on thermal conductivity and shear viscosity of strongly coupled dusty plasma in presence of asymmetric ion flow

Abstract

Thermal conductivity and shear viscosity are two important transport properties of dusty plasma. In dusty plasma asymmetric ion flow towards the sheath gives rise to a well known attractive oscillatory wake potential. The effect of ion flow induced wake potential and external magnetic field on thermal conductivity and shear viscosity in strongly coupled dusty plasmas have been reported in the present paper. Green-Kubo formalism along with Langevin dynamics simulation has been used to estimate thermal conductivity and shear viscosity of strongly coupled dusty plasma in presence of external magnetic field and attractive wake potential super-imposed with repulsive Debye-Hu¨ckel potential for a wide range of Coulomb coupling parameter (Γ), screening parameter (κ), neutral pressure (Nn) and magnetic field B. The study gives interesting results of transport properties of strongly coupled dusty plasma system.
