Abstract

We consider a Kubo oscillator whose stochasticity in frequency is generated by a 1.5-degree-of-freedom chaotic system. Based on the theory of multiplicative noise we show how fluctuation and decoherence and their relationship, which is analogous to the fluctuation-dissipation relation in many-body physics, can be realized in classical chaos. We numerically verify the basic theoretical propositions.
