Abstract
Equilibrium molecular dynamics (EMD) has been used to investigate diffusion coefficient (D) of 3D weakly coupled complex dusty plasma (WCCDP) by varying applied electric field (E). Velocity auto correlation function technique has been used to compute diffusion coefficient of dust particles. Impact of varying electric field has been tested for complete series of plasma parameters (Γ, κ) in a canonical ensemble. EMD simulation have been used to compute D for fixed number of particles (N = 500) at different values of plasma parameters (0.1≤ Γ≤ 0.9 and (1≤ κ ≤ 3). Computed results showed that value of D decreases by increasing Γ and increases by increasing E and κ. Simulation results also exposed that result obtained through Green-Kubo has same drift as previous results. But this work has some advancement due to E.
