Abstract
In this paper, the effects of colored correlations and asymmetry of the potential on the mean first-passage time (MFPT) are investigated for an asymmetric bistable system driven by multiplicative noise and additive noise. Numerical results show that the intensities of multiplicative and additive noises and the cross-correlation time τ affect the MFPT in the same way, the coupling strength λ and asymmetry r of the potential affect the MFPT in the same way. The increase of τ enhances the escape rate, while the increase of λ reduces the escape rate.
