Correlated cell movements drive epithelial finger formation
Sander C. Kammeraat, Yann-Edwin Keta, Paul Appleton +5
Epithelia form protective barriers in multicellular organisms. To maintain homeostasis, they must be able to regenerate and heal damaged areas. This occurs through collective cell…
Long-range order in two-dimensional systems with fluctuating active stresses
Yann-Edwin Keta, Silke Henkes
In two-dimensional tissues, such as developing germ layers, pair-wise forces (or active stresses) arise from the contractile activity of the cytoskeleton, with dissipation provided…
Emerging mesoscale flows and chaotic advection in dense active matter
Yann-Edwin Keta, Juliane Klamser, Robert L. Jack +1
We study two models of overdamped self-propelled disks in two dimensions, with and without aligning interactions. Active mesoscale flows leading to chaotic advection emerge in both…
Intermittent relaxation and avalanches in extremely persistent active matter
Yann-Edwin Keta, Rituparno Mandal, Peter Sollich +2
We use numerical simulations to study the dynamics of dense assemblies of self-propelled particles in the limit of extremely large, but finite, persistence times. In this limit, th…
Disordered collective motion in dense assemblies of persistent particles
Yann-Edwin Keta, Robert L. Jack, Ludovic Berthier
We explore the emergence of nonequilibrium collective motion in disordered non-thermal active matter when persistent motion and crowding effects compete, using simulations of a two…
Collective motion in large deviations of active particles
Yann-Edwin Keta, Étienne Fodor, Frédéric van Wijland +2
We analyse collective motion that occurs during rare (large deviation) events in systems of active particles, both numerically and analytically. We discuss the associated dynamical…
Translational and rotational velocities in shear-driven jamming of ellipsoidal particles
Yann-Edwin Keta, Peter Olsson
We study shear-driven jamming of ellipsoidal particles at zero temperature with a focus on the microscopic dynamics. We find that a change from spherical particles to ellipsoids wi…
Orientational Ordering in Athermally Sheared, Aspherical, Frictionless Particles
Theodore Marschall, Yann-Edwin Keta, Peter Olsson +1
We numerically simulate the uniform athermal shearing of bidisperse, frictionless, two dimensional spherocylinders and three dimensional prolate ellipsoids. We focus on the orienta…
