Image force on a charged projectile moving over a two-dimensional strongly coupled Yukawa system.
We use both analytical theory and numerical simulations to study the image force on a charged particle moving parallel to a two-dimensional strongly coupled Yukawa system. Special attention is paid to the effects of strong correlation and nonlinear response in the Yukawa system on the dependences of the image force on the particle velocity and its distance from the Yukawa system. Those effects are elucidated by comparing the results obtained from a Brownian dynamics simulation with those from linear-dielectric-response theories based on both the quasilocalized charge approximation and the standard Vlasov random phase approximation.
