Electroneutrality breakdown for electrolytes embedded in varying-section nanopores
P. Malgaretti, I. Pagonabarraga, J. Harting
We determine the local charge dynamics of a electrolyte embedded in a varying-section channel. By means of an expansion based on the length scale separation between the axial…
Active microrheology in corrugated channels: comparison of thermal and colloidal baths
P. Malgaretti, A. M. Puertas, I. Pagonabarraga
The dynamics of colloidal suspension confined within porous materials strongly differs from that in the bulk. In particular, within porous materials, the presence of boundaries wit…
Driving an electrolyte through a corrugated nanopore
Paolo Malgaretti, Mathijs Janssen, Ignacio Pagonabarraga +1
We characterize the dynamics of a electrolyte embedded in a varying-section channel. In the linear response regime, by means of suitable approximations, we derive the Onsager…
Bistability, oscillations and bidirectional motion of ensemble of hydrodynamically-coupled molecular motors
P. Malgaretti, I. Pagonabarraga, J. F. Joanny
We analyze the collective behavior of hydrodynamically coupled molecular motors. We show that the local fluxes induced by motors displacement can induce the experimentally observed…
Rectification and non-Gaussian diffusion in heterogeneous media
Paolo Malgaretti, Ignacio Pagonabarraga Miguel J. Rubi
We show that when Brownian motion takes place in a heterogeneous medium, the presence of local forces and transport coefficients leads to deviations from a Gaussian probability dis…
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…
