Stochastic Resonance on a Circle Without Periodic Excitation
-
Abstract
We analyse the appearance of coherent motion in the dynamics of the Langevin equation in the subtle case of I < 1, and show that stochastic resonance does exist even in the non-critical case I < 1. Moreover, we show the monotonicity of the rotation number and discuss the relationship between the center frequency of the power spectrum peak and the rotation number.
