一般噪声作用下极限环振子的动力学

Dynamics of Limit Cycle Oscillator Subject to General Noise

Denis S. Goldobin, Jun-nosuke Teramae, Hiroya Nakao, G. Bard Ermentrout

摘要:

相位描述是分析有噪声极限环振子的有力工具。然而,该方法迄今为止只发现有限的应用,因为目前的理论仅适用于高斯噪声,而现实世界中的噪声往往具有非高斯统计。在这里,我们提供了一般的,有色和非高斯,噪声,包括重尾噪声的极限环振荡器的相位减少。我们推导出的量化,如平均频率,扩散常数,和李雅普诺夫指数,以确认结果的一致性。应用我们的结果,我们还研究了相位和噪声之间的共振。

英文摘要:

The phase description is a powerful tool for analyzing noisy limit cycle oscillators. The method, however, has found only limited applications so far, because the present theory is applicable only to the Gaussian noise while noise in the real world often has non-Gaussian statistics. Here, we provide the phase reduction for limit cycle oscillators subject to general, colored and non-Gaussian, noise including heavy-tailed noise. We derive quantifiers like mean frequency, diffusion constant, and the Lyapunov exponent to confirm consistency of the result. Applying our results, we additionally study a resonance between the phase and noise.
