A Mesoscopic Approach to the ``Negative'' Viscosity Effect in Ferrofluids
A. Perez Madrid, T. Alarcon, J. M. G. Vilar +1
We present a mesoscopic approach to analyze the dynamics of a single magnetic dipole under the influence of an oscillating magnetic field, based on the formulation of a Fokker-Plan…
Periodic Modulation Induced Increase of Reaction Rates in Autocatalytic Systems
T. Alarcon, A. Perez-Madrid, J. M. Rubi
We propose a new mechanism to increase the reactions ratesin multistable autocatalytic systems. The mechanism is based upon the possibility for the enhancement of the response of t…
Stochastic Resonance in Nonpotential Systems
T. Alarcon, A. Perez-Madrid, J. M. Rubi
We propose a method to analytically show the possibility for the appearance of a maximum in the signal-to-noise ratio in nonpotential systems. We apply our results to the FitzHugh-…
Low Temperature Viscosity in Elongated Ferrofluids
T. Alarcon, A. Perez-Madrid, J. M. Rubi
We have studied the relaxation and transport properties of a ferrofluid in an elongational flow. These properties are influenced by the bistable nature of the potential energy. Bis…
