Slow dynamics and local quasi-equilibrium. Relaxation in supercooled colloidal systems
J. M. Rubi, I. Santamaria-Holek, A. Perez-Madrid
We present a Fokker-Planck description of supercooled colloidal systems exhibiting slow relaxation dynamics. By assuming the existence of a local quasi-equilibrium state during the…
Noise suppression by noise
J. M. G. Vilar, J. M. Rubi
We have analyzed the interplay between an externally added noise and the intrinsic noise of systems that relax fast towards a stationary state, and found that increasing the intens…
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…
Fokker-Planck Equations for Nucleation Processes Revisited
D. Reguera Lopez, J. M. Rubi, A. Perez-Madrid
We present a new approach to analyze homogeneous nucleation based on non-equilibrium thermodynamics. The starting point is the formulation of a Gibbs equation for the variations of…
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-…
