Controlling microalgae populations by phototactic memory
Gianni Jacucci, Davide Breoni, Pierre Illien +4
Understanding how microorganisms navigate in complex environments is a central question in active matter and biological physics. Phototaxis - the ability to use light as a navigati…
The effects of solvent quality and core wetting on the circularization of star polymers
Davide Breoni, Emanuele Locatelli, Luca Tubiana
We simulate the formation of cyclical arms in star polymers, focusing on the effects of solvent quality on their resulting linking complexity and gyration radius. We find that poly…
Effects of knotting on the collapse of active ring polymers
Davide Breoni, Emanuele Locatelli, Luca Tubiana
We use numerical simulations to study tangentially active flexible ring polymers with different knot topologies. Simple, unknotted active rings display a transition from an extende…
Conformation and topology of cyclical star polymers
Davide Breoni, Emanuele Locatelli, Luca Tubiana
We study the conformation and topological properties of cyclical star polymers with ring arms, each made of beads. We find that the conformational properties of unlinked cy…
Dynamical clustering and wetting phenomena in inertial active matter
Lorenzo Caprini, Davide Breoni, Anton Ldov +2
Dynamical clustering represents a characteristic feature of active matter consisting of self-propelled agents that convert energy from the environment into mechanical motion. At th…
