Wake potential in 2-D magnetized complex plasma

Abstract

Analytical expression for wake potential is obtained in a 2-D magnetized complex plasma using Linear Response Theory. The dynamics of the system is explored at moderate to relatively high magnetic field limit. A 2-D expression for wake potential is obtained and the variation in the strength of the wake potential is explored at different magnetic fields in moderate regime and for ion flow speed in supersonic regime. The theory also facilitates the understanding on the nature of wake potential in relatively high magnetic field limit. Molecular Dynamics simulation is performed to see the role of wake potential developed in this paper on governing the structural property of strongly coupled dusty plasma in presence of moderate to relatively strong magnetic field.
