Continuum description of confluent tissues with spatial heterogeneous activity
Fernanda Pérez-Verdugo, Rodrigo Soto
A continuum description is built to characterize the stationary and transient deformations of confluent tissues subject to heterogeneous activities. By defining a coarse-grained te…
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…
Diversity of self-propulsion speeds reduces motility-induced clustering in confined active matter
Pablo de Castro, Francisco M. Rocha, Saulo Diles +2
Self-propelled swimmers such as bacteria agglomerate into clusters as a result of their persistent motion. In 1D, those clusters do not coalesce macroscopically and the stationary…
Modelling of active contraction pulses in epithelial cells using the vertex model
Fernanda Pérez-Verdugo, Germán Reig, Mauricio Cerda +2
Several models have been proposed to describe the dynamics of epithelial tissues undergoing morphogenetic changes driven by apical constriction pulses, which differ in where the co…
Stability of the homogeneous steady state for a model of a confined quasi-two-dimensional granular fluid
Vicente Garzó, Ricardo Brito, Rodrigo Soto
A linear stability analysis of the hydrodynamic equations of a model for confined quasi-two-dimensional granular gases is carried out. The stability analysis is performed around th…
