Active Brownian particle movement and their cluster formation

MD simulation of self propulling Brownian particles

Number of particles used = 4096 dt = 0.00001 Time steps for equilibriation = 1000000 Total time steps = 2000000 Density of a single ensemble = 0.80 vp : Propulsion Velocity

The code is parallelized using OpenMP

Brownian particles interact with each other via the modified Lennard-Jones potential known as the WCA potential This is also called soft active Browian simulation Cut off distance for the potential is 2^(1/6)

Trajectory of the particle is determined using Langevin equations
