Issue Date: | 18-Feb-2009 | Citation: | European Physical Journal B 69: 19-22 (2009) | Abstract: | We study the effects of the confining conditions on the occurrence of stochastic resonance (SR) in continuous bistable systems. We model such systems by means of double-well potentials that diverge like |x|q for |x| →∞. For super-harmonic (hard) potentials with q > 2 the SR peak sharpens with increasing q, whereas for sub-harmonic (soft) potentials, q < 2, it gets suppressed. | Description: | 5 pages, 1 figure.-- PACS nrs.: 05.40.-a; 02.50.Ey.
