Spontaneous motion of a passive fluid droplet in an active microchannel
A. Tiribocchi, M. Durve, M. Lauricella +2
We numerically study the dynamics of a passive fluid droplet confined within a microchannel whose walls are covered with a thin layer of active gel. The latter represents a fluid o…
Crystallization and topology-induced dynamical heterogeneities in soft granular clusters
Michal Bogdan, Jesus Pineda, Mihir Durve +4
Soft-granular media, such as dense emulsions, foams or tissues, exhibit either fluid- or solid-like properties depending on the applied external stresses. Whereas bulk rheology of…
Shapes and dynamic regimes of a polar active fluid droplet under confinement
Adriano Tiribocchi, Mihir Durve, Marco Lauricella +3
Active droplets are artificial microswimmers built from a liquid dispersion by microfluidic tools and showing self-propelled motion. These systems hold particular interest for mimi…

Andrea Montessori, Marco Lauricella, Adriano Tiribocchi +2
One of the most distinctive hallmarks of many-body systems far from equilibrium is the spontaneous emergence of order under conditions where disorder would be plausibly expected. H…
