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.

Geometric Stochastic Resonance [PDF]
Physical Review Letters, 2010 A Brownian particle moving across a porous membrane subject to an oscillating force exhibits stochastic resonance with properties which strongly depend on the geometry of the confining cavities on the two sides of the membrane. Such a manifestation of stochastic resonance requires neither energetic nor entropic barriers, and can thus be regarded as a ...

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.

Coherent stochastic resonance [PDF]
Physical Review E, 1995 We consider Brownian motion on a line terminated by two trapping points. A bias term in the form of a telegraph signal is applied to this system. It is shown that the first two moments of survival time exhibit a minimum at the same resonant frequency.

Single-Molecule Stochastic Resonance
Physical Review X, 2012 Stochastic resonance (SR) is a well-known phenomenon in dynamical systems. It consists of the amplification and optimization of the response of a system assisted by stochastic (random or probabilistic) noise.

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
