Stochastic resonance in a suspension of magnetic dipoles under shear flow - art. no. 041112

We show that a magnetic dipole in a shear flow under the action of an oscil lating magnetic field displays stochastic resonance in the linear response regime. To this end, we compute the classical quantifiers of stochastic res onance, i.e., the signal to noise ratio, the escape time distribution, and the mean first passage time. We also discuss the limitations and role of th e linear response theory in its applications to the theory of stochastic re sonance.
