Numerical Simulation of Optical Trap Systems

The current work deals with numerical simulation of optical trap systems at time scales varying from very small to very large. This analysis is important to understand the effects of different forces acting on the optically trapped particle. The significance of inertia forces are also evaluated at these time scales. A novel method of computing diffusion coefficient from the simulated values is proposed. It has been shown that the computed values of the diffusion coefficient are an exact match to the theoretical results.
