A ratchet driven by quasimonochromatic noise
M. Arrayas, R. Mannella, P. V. E. McClintock +2
The currents generated by noise-induced activation processes in a periodic potential are investigated analytically, by digital simulation and by performing analogue experiments.
Noise-Induced Linearisation and Delinearisation
MI Dykman, DG Luchinsky, R Mannella +4
It is demonstrated, by means of analogue electronic simulation and theoretically, that external noise can markedly change the character of the response of a nonlinear system to a l…
Supernarrow Spectral Peaks and High Frequency Stochastic Resonance in Systems with Coexisting Periodic Attractors
MI Dykman, DG Luchinsky, R Mannella +3
The kinetics of a periodically driven nonlinear oscillator, bistable in a nearly resonant field, has been investigated theoretically and through analogue experiments. An activation…
Linear Response Theory in Stochastic Resonance
MI Dykman, H Haken, Gang Hu +6
The susceptibility of an overdamped Markov system fluctuating in a bistable potential of general form is obtained by analytic solution of the Fokker-Planck equation (FPE) for low n…
High Frequency Stochastic Resonance in Periodically Driven Systems
M. I. Dykman, D. G. Luchinsky, R. Mannella +4
High frequency stochastic resonance (SR) phenomena, associated with fluctuational transitions between coexisting periodic attractors, have been investigated experimentally in an el…
Stochastic Resonance
M. I. Dykman, D. G. Luchinsky, R. Mannella +4
Stochastic resonance (SR) - a counter-intuitive phenomenon in which the signal due to a weak periodic force in a nonlinear system can be {\it enhanced} by the addition of external…
