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

Intrinsic periodic and aperiodic stochastic resonance in an electrochemical cell.
TL;DR: The scanning electron microscope images for the electrode metal surfaces are shown to corroborate the emergence of order as a result of the interaction between the nonlinear dynamics and the composite signal.

Stochastic resonance for nonequilibrium systems
TL;DR: In this article, a general mathematical framework based on large deviation theory and specifically on the theory of quasipotentials is proposed for describing stochastic resonance (SR) in noisy N-dimensional nonequilibrium systems possessing two metastable states and undergoing a periodically modulated forcing.

Collective stochastic resonance behavior in the globally coupled fractional oscillator
TL;DR: In this paper, the collective stochastic resonance (SR) behavior of globally coupled fractional Langevin equations with multiplicative noise and external signal was investigated, and the authors showed that collective SR behavior versus noise intensity can ensue when system parameters satisfy the necessary and sufficient conditions; this notion means that we can control the collective SR of our fractional dynamic model by properly adjusting the system parameters within a certain range.

Bistable sensors based on broken symmetry phenomena: The residence time difference vs. the second harmonic method
TL;DR: In this paper, the second harmonic and the mean residence time difference (RTD) were used for the estimation of the power spectrum in the presence of bistable noisy sensors.
