correlation between the two Wiener processes, which model the two white noise sources. This model can be useful to describe the … noise on the statistical properties of the escape time with reference to the noise enhanced stability (NES) phenomenon, that … is the noise induced enhancement of the lifetime of a metastable state. We observe NES effect in our model with …

-reversible noise is analyzed. The calculation of the effective diffusion coefficient is reduced to the mean first passage time problem … supersymmetric potential modulated by: (i) an external white Gaussian noise and (ii) a Markovian dichotomous noise. For both cases … in the absence of thermal noise. For rectangular potential the diffusion slows down, for all parameters of noise and of …

The energy diffusion controlled reaction rate of a reacting particle with linear weak damping and broad-band noise … oscillators under broad-band noise excitation using generalized harmonic functions is briefly introduced. Then, the reaction rate … of the classical Kramers' reacting model with linear weak damping and broad-band noise excitation is investigated by …
