Entropically-induced asymmetric passage times of charged tracers across corrugated channels
Paolo Malgaretti, Ignacio Pagonabarraga, Miguel J Rubi
We analyze the diffusion of charged and neutral tracers suspended in an electrolyte embedded in a channel of varying cross-section. Making use of systematic approximations, the dif…
Confined Brownian ratchets
Paolo Malgaretti, Ignacio Pagonabarraga, J. Miguel Rubi
We analyze the dynamics of Brownian ratchets in a confined environment. The motion of the particles is described by a Fick-Jakobs kinetic equation in which the presence of boundari…
Controlling anomalous stresses in soft field-responsive systems
D. Reguera, J. M. Rubí, A. Pérez-Madrid
We report a new phenomenon occurring in field-responsive suspensions: shear-induced anomalous stresses. Competition between a rotating field and a shear flow originates a multiplic…
