Langevin dynamics (source code)

= Langevin dynamics

<Langevin dynamics> describes a dynamical variable driven by deterministic forces and random noise. <Underdamped Langevin dynamics> retains inertia, whereas <Overdamped Langevin dynamics> neglects it. At <thermal equilibrium>, the <fluctuation-dissipation relation for a Langevin particle> relates <Gaussian white noise> strength to drag and <temperature>.
