FIG. 1.

(Color online) Main panel: probability distribution function [see Eq. (9)] for several supercriticalities . Nonlinear damping coefficient and noise level . Inset: dependence of the mean oscillator power [see Eq. (10)] on the supercriticality for several noise levels . Nonlinear damping coefficient .

FIG. 2.

(Color online) Main panel: dependence of the mean power on the bias current . Dots—experiment of Ref. 9 for , solid line—theoretical dependence [Eq. (10)] for , , and . The inset shows the same data for the inverse power in near-threshold range of currents. Dashed line corresponds to the approximate expression Eq. (11) valid for small currents. Intersection of this line with gives the value of the threshold current .
