TLDR
The first observation of stochastic resonance in an optical device, the bidirectional ring laser, is reported and the addition of injected noise can lead to an improved signal-to-noise ratio.Abstract:
We report the first observation of stochastic resonance in an optical device, the bidirectional ring laser. The experiment exploits a new technique to modulate periodically the asymmetry between the two counter-rotating lasing modes. The measurements verify that the addition of injected noise can lead to an improved signal-to-noise ratio (relative to that observed with no externally injected noise).read more

Aperiodic Stochastic Resonance in the Fractional-Order Bistable System
Chengjin Wu,Qing Jiao,Feng Tian +2 more
TL;DR: The general scale transformation is introduced, and the equivalent system with large system parameters is able to match the input character signal with arbitrary small pulse width well, where the scale parameter is a key to achieve resonance.

Noise enhanced the preponderant oscillation
TL;DR: The z-variable's output signal-to-noise ratio (SNR) as a function of the noise intensity shows non-monotonic behavior, indicating the occurrence of EISSR.

Frictional trajectories near a barrier: A dissipationless Newtonian approach
TL;DR: In this paper, the problem of classical frictional motion under a potential possessing a barrier is addressed, and the Green's solution of the exact equation of motion can be reduced to an improved Rayleigh form or a non-Rayleigh form, the latter being outside the scope of the standard large-friction treatment of the Fokker-Planck equation.
