Active Matter Clusters at Interfaces

  title={Active Matter Clusters at Interfaces},
  author={Katherine Copenhagen and Ajay Gopinathan},
  journal={arXiv: Biological Physics},
Collective and directed motility or swarming is an emergent phenomenon displayed by many self-organized assemblies of active biological matter such as clusters of embryonic cells during tissue development, cancerous cells during tumor formation and metastasis, colonies of bacteria in a biofilm, or even flocks of birds and schools of fish at the macro-scale. Such clusters typically encounter very heterogeneous environments. What happens when a cluster encounters an interface between two…

Frustration-induced phases in migrating cell clusters

An agent-based model is developed in which the cells form a cohesive cluster due to attractive and alignment interactions, and it is found that when cells at the cluster rim are more motile, all three phases of motion coexist, in agreement with observations.

Topologically induced swarming phase transition on a 2D percolated lattice

There is a finite range of topological disorder where swarming can occur and that this range can be maximized by an optimal amount of mutual repulsion, and it is found that the swarming transition does not exist in the large system size limit, while the addition of a mutually repulsive interaction can restore the existence of the transition at a finite critical value of disorder.

Guidance of collective cell migration by substrate geometry.

The results show that the geometrical confinement of cells into well-defined circles induces a persistent, coordinated and synchronized rotation of cells that depends on cell density, which is strongly altered in cells that present a downregulation of adherens junctions and in cancerous cell types.

Motility of Escherichia coli cells in clusters formed by chemotactic aggregation

A simulation based on a model of the sensory memory of E. coli reproduces the experimental data and indicates that the tumble rate and consequently the morphology of the cluster are determined by the sensoryMemory of cells.

This review presents the related experimental observations and treat them in light of a few basic computational models so as to make an interpretation of the phenomena at a quantitative level as well.

Phase transition in the collective migration of tissue cells: experiment and model.

A flocking model is constructed that exhibits a continuous transition to the ordered phase, while assuming only short-range interactions and no explicit information about the knowledge of the directions of motion of neighbors.

Emergent dynamics of laboratory insect swarms

Three-dimensional, time-resolved measurements of the positions, velocities and accelerations of individual insects in laboratory swarms of the midge Chironomus riparius show that the swarms display an effective large-scale potential that keeps individuals bound together and characterize the shape of this potential.

Hydrodynamics of soft active matter

This review summarizes theoretical progress in the field of active matter, placing it in the context of recent experiments, and highlights the experimental relevance of various semimicroscopic derivations of the continuum theory for describing bacterial swarms and suspensions, the cytoskeleton of living cells, and vibrated granular material.

Gregarious vs Individualistic Behavior in Vicsek Swarms and the Onset of First-Order Phase Transitions

The Standard Vicsek Model (SVM) is a minimal nonequilibrium model of selfpropelled particles that appears to capture the essential ingredients of critical flocking phenomena. In the SVM, particles

Optimal noise maximizes collective motion in heterogeneous media.

It is shown that while at low obstacle densities the system exhibits long-range order, in strongly heterogeneous media collective motion is quasi-long-range and exists only for noise values in between two critical values, with the system being disordered at both large and low noise amplitudes.
