Mean first-passage time in a bistable system driven by strongly correlated noise: Introduction of a fluctuating potential

The theories of Tsironis and Grigolini [Phys. Rev. Lett. 61, 7 (1988); Phys. Rev. A 38, 3749 (1988)] and of de la Rubia et al. [Phys. Rev. A 38, 3827 (1988)] are discussed. A comparision with a digital simulation is made, and interesting conclusions on the application of a fluctuating potential to bistable systems driven by strongly correlated noise are drawn.
