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…
Critical habitat size of organisms diffusing with stochastic resetting
Luiz Menon, Pablo de Castro, Celia Anteneodo
The persistence of populations depends on the minimum habitat area required for survival, known as the critical patch size. While most studies assume purely diffusive movement, add…
Effects of kinetic energy on heat fluctuations of passive and active overdamped driven particles
Pedro V. Paraguassú, Rui Aquino, Pablo de Castro
To describe the spatial trajectory of an overdamped Brownian particle, inertial effects can be neglected. Yet, at the energetic level of stochastic thermodynamics, changes in kinet…
Restoring the fluctuation-dissipation theorem in Kardar-Parisi-Zhang universality class through a new emergent fractal dimension
Márcio S. Gomes-Filho, Pablo de Castro, Danilo B. Liarte +1
The Kardar-Parisi-Zhang (KPZ) equation describes a wide range of growth-like phenomena, with applications in physics, chemistry and biology. There are three central questions in th…
Movement bias in asymmetric landscapes and its impact on population distribution and critical habitat size
Vivian Dornelas, Pablo de Castro, Justin M. Calabrese +2
Ecologists have long investigated how demographic and movement parameters determine the spatial distribution and critical habitat size of a population. However, most models oversim…
Sequential epidemic spread between agglomerates of self-propelled agents in one dimension
Pablo de Castro, Felipe Urbina, Ariel Norambuena +1
Motile organisms can form stable agglomerates such as cities or colonies. In the outbreak of a highly contagious disease, the control of large-scale epidemic spread depends on fact…
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…
Spinning rigid bodies driven by orbital forcing: The role of dry friction
Pablo de Castro, Tiago Araújo Lima, Fernando Parisio
A "circular orbital forcing" makes a chosen point on a rigid body follow a circular motion while the body spins freely around that point. We investigate this problem for the planar…
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…
