Stochastic resonance in a suspension of magnetic dipoles under shear flow
Alarcón, Tomás; Pérez Madrid, Agustín
Universitat de Barcelona
We show that a magnetic dipole in a shear flow under the action of an oscillating magnetic field displays stochastic resonance in the linear response regime. To this end, we compute the classical quantifiers of stochastic resonance, 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 the linear response theory in its applications to the theory of stochastic resonance.
