Physical Review Letters, 1994
We demonstrate that stochastic resonance, where an increase in the noise acting on a nonlinear dynamical system increases the signal-to-noise ratio describing the response to periodic driving, can occur in quantum systems as well as classical ones.

Physical Review Letters, 2000
We report the effect of doubly stochastic resonance which appears in nonlinear extended systems if the influence of noise is twofold: A multiplicative noise induces bimodality of the mean field of the coupled network and an independent additive noise governs the dynamic behavior in response to small periodic driving.

Stochastic resonance has been observed in many forms of systems, and has been hotly debated by scientists for over 30 years. Applications incorporating aspects of stochastic resonance may yet prove revolutionary in fields such as distributed sensor networks, nano-electronics, and biomedical prosthetics.

Controlling Stochastic Resonance
Physical Review Letters, 1999Stochastic 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 ...

Stochastically Perturbed Resonance
SIAM Journal on Applied Mathematics, 1981We 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.

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 paramagnetic resonance systems
Journal of Statistical Physics, 1993Experimental 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.

In the 1980's, people discovered that certain nonlinear systems showed improved coherence with the addition of random noise. We present the theory of stochastic resonance at a quantitative level suitable for graduate students in the physical sciences.

Minireview of stochastic resonance
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1998We present an introductory overview of the subject of stochastic resonance. As researchers’ interest in the phenomenon has spread from physics to biology, new questions both fundamental and practical have emerged. After reviewing some key aspects of the subject, we describe a promising candidate for exploring the possible beneficial effects of random ...

Analysis of stochastic resonances
Physical Review E, 2003We investigate the one-dimensional diffusion of a particle in a piecewise linear potential superimposed with a step of a harmonically modulated height. Employing the matching conditions, we solve the corresponding Fokker-Planck equation and we analyze nonlinear features of the particle's mean position as a function of time.
