This system consists of two Brownian spherical particles that interact through an elastic potential and have time-dependent radii. We suggest an algorithm by which the sizes of the particles can be varied, such that the center of mass of the system is able to move at an average constant speed in one direction. The dynamics of the system is studied theoretically using a Langevin model, as well as from Brownian Dynamics simulations.enBrownian motionBrownian dynamicsCenter of mass (relativistic)Langevin dynamicsStatistical physicsPhysicsConstant (computer programming)Brownian motorClassical mechanicsLangevin equationarticle
