Controlling Stochastic Resonance

Physical Review Letters, 1999
Stochastic resonance (SR) is a nonlinear noise-mediated cooperative phenomenon wherein the coherent response to a deterministic signal can be enhanced in the presence of an optimal amount of noise. Since its inception in 1981 [1], SR [2] has been demonstrated in diverse systems including sensory neurons, mammalian neuronal tissue, lasers, SQUIDs ...

Stochastic resonance on a circle

Physical Review Letters, 1994
We describe a new realization of stochastic resonance, applicable to a broad class of systems, based on an underlying excitable dynamics with deterministic reinjection. A simple but general theory of such ``single-trigger'' systems is compared with analog simulations of the Fitzhugh-Nagumo model, as well as experimental data obtained from stimulated ...

Stochastic resonance in paramagnetic resonance systems

Journal of Statistical Physics, 1993
Experimental evidence of the stochastic resonance phenomenon in an electron paramagnetic resonance (EPR) system is reported. The amplitude and phase response of the EPR system operating in bistable conditions are measured for increasing values of the noise intensity.

Stochastic Resonance as aBona FideResonance

Physical Review Letters, 1995
Stochastic resonance in a bistable potential is fully characterized as a synchronization effect of the hopping mechanism induced by the external periodic bias. Most notably, synchronization is shown to attain a maximum by increasing the forcing frequency close to the relevant switching rate, thus revealing a bona fide resonant process.

Stochastically Perturbed Resonance

SIAM Journal on Applied Mathematics, 1981
We analyze the motion of a periodically forced oscillator whose natural frequency is the superposition of a slowly varying component and a small stochastic perturbation. When the slowly varying component of natural frequency passes through the value corresponding to the forcing, there is resonance.

Stochastic giant resonance

Physical Review E, 2007
The model of an electric circuit with dichotomous resistance is investigated. It is shown that the dichotomous resistance can induce a phenomenon of stochastic giant resonance for the signal-to-noise ratio (SNR) as a function of input signal frequency.

STOCHASTIC RESONANCE IN CHUA'S CIRCUIT

International Journal of Bifurcation and Chaos, 1992
In this paper, we report numerical observations of the stochastic resonance (SR) phenomenon in a bistable chaotic electronic circuit (namely, Chua’s circuit) driven simultaneously by noise and a sinusoidal signal. It is shown that the noise-induced “chaos-chaos” type intermittency is a physical mechanism of the SR-phenomenon in chaotic systems.

Comparison of stochastic adaptation and stochastic resonance

Physical Review E
Stochastic resonance is a phenomenon possessed by some nonlinear oscillators, in which a weak signal is boosted by noise. Both the monostable and bistable Duffing oscillators can exhibit this property. However, stochastic resonance has a strong frequency-dependence, as only a band of frequencies may be boosted by noise.

Noise-Induced Resonances: Stochastic Resonance, Resonant Activation, and Stochastic Ratchets

2018
Our world is replete with noises. In common sense a noise is a nuisance that blocks coherence; you feel annoyed with ambient sound noises when listening to music. In this chapter we will study a counter-intuitive phenomenon, called stochastic resonance (SR) , where a periodically modulated perturbation or signal too weak to be detected can be enhanced ...
