Abstract

We study the instability of a harmonic oscillator subject to additive and dichotomous multpicalive noise, focusing on the dependence of the instability threshold on the mass. For multiplicative noise in the damping, the energy instability threshold is crossed as the mass is decreased, as long as the smaller damping is in fact negative. For multiplicative noise in the stifness, the situation is more complicate and in fact the energy transition is reentrant for intermidiate noise strength and damping. For multiplicative noise of the mass, taking the velocity to be conserved as the mass is changed, we find that increasing the mass destabilizes the system.
