Self Diffusion of Yukawa system in presence of external magnetic field

Diffusion of dust particles is one of the most significant transport processes of strongly coupled dusty plasma that reflect the nature of inter particle interaction and characterize thermodynamics of the system. In this paper the effect of magnetic field on diffusion of dust particles in strongly coupled dusty plasma is investigated by using molecular dynamics simulations. Self- diffusion coefficients of Yukawa systems are obtained for a wide range of plasma parameters and magnetic field strength using Green- Kubo expression which is based on integrated velocity autocorrelation function (VACF). It is assumed that dust particles interact with each other by modified Yukawa (i.e. screened Coulomb) potential. The study gives interesting results of dust particle diffusion in magnetized plasma.
