标题： Pseudopotential of birhythmic van der Pol type systems with correlated noise

摘要： 我们提出在存在相关噪声的情况下，计算双周期系统——类似范德波尔振荡器——的有效活化能，通常称为伪势或准势。 通过分析方法和数值模拟证明，可以考虑相关噪声，并能够恢复逃逸的低噪声速率。 因此，我们得出结论，伪势或有效活化能对于双周期吸引子的稳定性来说是一个现实的描述，即使在存在相关噪声的情况下也是如此。 显示英文摘要

摘要： We propose to compute the effective activation energy, usually referred to a pseudopotential or quasipotential, of a birhythmic system -- a van der Pol like oscillator -- in the presence of correlated noise. It is demonstrated, with analytical techniques and numerical simulations, that the correlated noise can be taken into account and one can retrieve the low noise rate of the escapes. We thus conclude that a pseudopotential, or an effective activation energy, is a realistic description for the stability of birhythmic attractors also in the presence of correlated noise.
