Figure 2.

Stochastic switching of the nonlinear resonator with a diameter of 5 μm. (a) Amplitude as a function of time for an effective temperature T_eff = 25 × 10³ K, showing a total of 8 fluctuation-induced transitions. The right-hand side of the figure shows a histogram of the amplitude. (b) Amplitude in the P-Q space for T_eff = 25 × 10³ K, each point is one sample of the measurement in part a. (c) Rate of up and down transitions as a function of effective temperature, fitted with Kramer’s law (eq 4), two sets of consecutive measurements are shown to check for consistency. (d) Amplitude as a function of time for an effective temperature T_eff = 65 × 10³ K, showing a total of 502 transitions. The right-hand side of the figure shows a histogram of the amplitude. (e) Amplitude in the P-Q space for T_eff = 65 × 10³ K. f) Residence time distributions for both states at T_eff = 65 × 10³, a Poisson distribution (eq 5) is fitted to the data and gives a transition time τ_k = 1.7 ms, corresponding to a transition rate r_k = 0.58 kHz.
