Spinor stochastic resonance [PDF]
Physical Review B, 2015 We report on noise-induced-spin-ordering in a collective quasipaticle system: spinor stochastic resonance. Synergetic interplay of a polarization-modulated signal and a polarization-noise allows us to switch coherently between the two metastable states of a microcavity-polariton spin bistable system.

Mechanoreceptors and Stochastic Resonance
Scholarpedia, 2008 Stochastic Resonance (SR) is a counterintuitive phenomenon whereby noise under appropriate conditions can enhance the detection of weak signals rather than interfering with signal transmission. Originally described in nonlinear physical systems, SR is applicable as well for biological processes that are also frequently nonlinear.

Detection of Single Molecules Using Stochastic Resonance of Bistable Oligomers
Nanomaterials, 2020 Ultra-sensitive elements for nanoscale devices capable of detecting single molecules are in demand for many important applications. It is generally accepted that the inevitable stochastic disturbance of a sensing element by its surroundings will limit ...

A New Piecewise Nonlinear Asymmetry Bistable Stochastic Resonance Model for Weak Fault Extraction
Machines, 2022 In order to solve output saturation problems found in traditional stochastic resonance methods and to improve the diagnosis ability of weak faults, a new piecewise nonlinear asymmetric bistable stochastic resonance (PNABSR) method is proposed. This model

The Stochastic Resonance Phenomenon of Different Noises in Underdamped Bistable System
Advances in Mathematical Physics, 2021 In this paper, the stochastic resonance (SR) phenomenon of four kinds of noises (the white noise, the harmonic noise, the asymmetric dichotomous noise, and the Lévy noise) in underdamped bistable systems is studied.

On square-wave-driven stochastic resonance for energy harvesting in a bistable system
AIP Advances, 2014 Stochastic resonance is a physical phenomenon through which the throughput of energy within an oscillator excited by a stochastic source can be boosted by adding a small modulating excitation.
