Casademunt, J. and Mannella, R. and McClintock, Peter V. E. (1987) Relaxation times of non-Markovian processes. Physical Review A, 35 (12). pp. 5183-5190. ISSN 1050-2947
We consider a general class of non-Markovian processes defined by stochastic differential equations with Ornstein-Uhlenbeck noise. We present a general formalism to evaluate relaxation times associated with correlation functions in the steady state. This formalism is a generalization of a previous approach for Markovian processes. The theoretical results are shown to be in satisfactory agreement both with experimental data for a cubic bistable system and also with a computer simulation of the Stratonovich model. We comment on the dynamical role of the non-Markovianicity in different situations.
