Brownian Motion: Langevin Equation - Göteborgs universitet
physics.gu.se6.1 Langevin equation Consider a large particle (the Brownian particle) immersed in a uid of much smaller particles (atoms). Here the radius of the Brownian particle is typically 10 9m <a< 5 10 7m. The agitated motion of the large particle is much slower than that of the atoms and is the result of random and rapid collisions due to density
