Brownian Motion (Oscillator)

  • Wilhelm Brenig
Chapter

Abstract

A second simple and important example is the Brownian motion of a harmonic oscillator [5.1–3]. Calling the displacement of the oscillator from its equilibrium position (X 0 = 0) X(t), one obtains the equation of motion in the presence of an external force f e
$$m\left( {\ddot X + \omega _0^2X + \gamma X} \right) = {f^e}\left( t \right).$$
