Will the energy of a randomly driver harmonic oscillator grow to infinity or...
The equation of motion for an undamped harmonic oscillator, with driver $ f=f(t)$ is given by: $ $ \ddot{x}+x=f.$ $ Let the initial conditions be given by: $ $ x(0)=\dot{x}(0)=0.$ $ If $ f=\cos(t)$...

View ArticleHow to code oscillator driven by Gaussian white noise?
I have written some python code which was designed to try to solve the following differential equation: $ $ \ddot{x}+\omega_0^2x=\eta(t),$ $ where $ \eta(t)$ is the gaussian white noise, with mean 0...
