Geometric stochastic resonance
journal contribution
posted on 2013-07-10, 08:45 authored by Pulak Kumar Ghosh, Fabio Marchesoni, Sergey SavelievSergey Saveliev, Franco NoriA 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 purely geometric effect. The magnitude of this effect is sensitive to the geometry of both the cavities and the pores, thus leading to distinctive optimal synchronization conditions.
