Phoretic colloids close to and trapped at fluid interfaces

Paolo Malgaretti, Jens Harting

The active motion of phoretic colloids leads them to accumulate at boundaries and interfaces. Such an excess accumulation, with respect to their passive counterparts, makes the dyn…

Antiresonant driven systems for particle manipulation

M. Florencia Carusela, Paolo Malgaretti, J. Miguel Rubi

We report on the onset of anti-resonant behaviour of mass transport systems driven by time-dependent forces. Anti-resonances arise from the coupling of a sufficiently high number o…

Active polymer rings: activity-induced collapse and dynamical arrest

Emanuele Locatelli, Valentino Bianco, Paolo Malgaretti

We investigate, using numerical simulations, the conformations of isolated active ring polymers. We find that the their behaviour depends crucially on their size: short rings ($N \…

Transport of neutral and charged nanorods across varying-section channels

Paolo Malgaretti, Jens Harting

We study the dynamics of neutral and charged rods embedded in varying-section channels. By means of systematic approximations, we derive the dependence of the local diffusion coeff…

Inhomogeneous surface tension of chemically active fluid interfaces

Alessio Squarcini, Paolo Malgaretti

We study the dependence of the surface tension of a fluid interface on the density profile of a third suspended phase. By means of an approximated model for the binary mixture and…

Polymer translocation across a corrugated channel: Fick-Jacobs approximation extended beyond the mean first passage time

Paolo Malgaretti, Gleb Oshanin

Polymer translocation across a corrugated channel is a paradigmatic stochastic process encountered in diverse systems. The instance of time when a polymer first arrives to some pre…
