MIPS is a Maxwell fluid with an extended and non-monotonic crossover
José Martín-Roca, Chantal Valeriani, Kristian Thijssen +2
Understanding the mechanical properties of active suspensions is crucial for their potential applications in materials engineering. Among the various phenomena in active matter tha…
Self-assembly of active amphiphilic Janus particles
S. A. Mallory, F. Alarcon, A. Cacciuto +1
In this article, we study the phenomenology of a two dimensional dilute suspension of active amphiphilic Janus particles. We analyze how the morphology of the aggregates emerging f…
An active approach to colloidal self-assembly
S. A. Mallory, C. Valeriani, A. Cacciuto
In this review we discuss recent advances in the self-assembly of self-propelled colloidal particles and highlight some of the most exciting results in this field with a specific f…
Microphase separation in two dimensional suspensions of self-propelled spheres and dumbbells
Clarion Tung, Joseph Harder, Chantal Valeriani +1
We use numerical simulations to study the phase behavior of self-propelled spherical and dumbbellar particles interacting via micro-phase separation inducing potentials. Our result…
Anomalous dynamics of an elastic membrane in an active fluid
S. A. Mallory, C. Valeriani, A. Cacciuto
Using numerical simulations, we characterized the behavior of an elastic membrane immersed in an active fluid. Our findings reveal a nontrivial folding and re-expansion of the memb…
Activity induced collapse and re-expansion of rigid polymers
Joseph Harder, Chantal Valeriani, Angelo Cacciuto
We study the elastic properties of a rigid filament in a bath of self-propelled particles. We find that while fully flexible filaments swell monotonically upon increasing the stren…
The role of particle shape in active depletion
J. Harder, S. A. Mallory, C. Tung +2
Using numerical simulations, we study how a solution of small active disks, acting as depletants, induces effective interactions on large passive colloids. Specifically, we analyze…
Curvature Induced Activation of a Passive Tracer in an Active Bath
S. A. Mallory, C. Valeriani, A. Cacciuto
We use numerical simulations to study the motion of a large asymmetric tracer immersed in a low density suspension of self-propelled nanoparticles in two dimensions. Specifically,…
Living clusters and crystals from low density suspensions of active colloids
B. M. Mognetti, A. Šarić, S. Angioletti-Uberti +3
Recent studies aimed at investigating artificial analogs of bacterial colonies have shown that low-density suspensions of self-propelled particles confined in two dimensions can as…
Anomalous Thermomechanical Properties of a Self-propelled Colloidal Fluid
S. A. Mallory, A. Šarić, C. Valeriani +1
We use numerical simulations to compute the equation of state of a suspension of spherical, self-propelled nanoparticles. We study in detail the effect of excluded volume interacti…
Phase separation and rotor self-assembly in active particle suspensions
J. Schwarz-Linek, C. Valeriani, A. Cacciuto +4
Adding a non-adsorbing polymer to passive colloids induces an attraction between the particles via the `depletion' mechanism. High enough polymer concentrations lead to phase separ…
