Collective ballistic motion explains fast aggregation in adhesive active matter
Emanuel F. Teixeira, Pablo de Castro, Carine P. Beatrici +2
Inspired by motile cells in tissue formation, we find that active systems of self-aligning adhesive particles undergo ballistic aggregation through a flocking transition. This kine…
Wetting dynamics by mixtures of fast and slow self-propelled particles
Mauricio Rojas-Vega, Pablo de Castro, Rodrigo Soto
We study active surface wetting using a minimal model of bacteria that takes into account the intrinsic motility diversity of living matter. A mixture of "fast" and "slow" self-pro…
Mixtures of self-propelled particles interacting with asymmetric obstacles
Mauricio Rojas-Vega, Pablo de Castro, Rodrigo Soto
In the presence of an obstacle, active particles condensate into a surface "wetting" layer due to persistent motion. If the obstacle is asymmetric, a rectification current arises i…
Phase separation of mixtures after a second quench: composition heterogeneities
Pablo de Castro, Peter Sollich
We investigate binary mixtures undergoing phase separation after a second (deeper) temperature quench into two- and three-phase coexistence regions. The analysis is based on a latt…
Critical phase behavior in multi-component fluid mixtures: Complete scaling analysis
Pablo de Castro, Peter Sollich
We analyze the critical gas-liquid phase behavior of arbitrary fluid mixtures in their coexistence region. We focus on the setting relevant for polydisperse colloids, where the ove…
Phase separation dynamics of polydisperse colloids: a mean-field lattice-gas theory
Pablo de Castro, Peter Sollich
New insights into phase separation in colloidal suspensions are provided via a new dynamical theory based on the Polydisperse Lattice-Gas model. The model gives a simplified descri…
