Active glasses

LMC Janssen - Journal of Physics: Condensed Matter, 2019 - iopscience.iop.org
Active glassy matter has recently emerged as a novel class of non-equilibrium soft matter,
combining energy-driven, active particle movement with dense and disordered glass-like …

Dense active matter model of motion patterns in confluent cell monolayers

S Henkes, K Kostanjevec, JM Collinson… - Nature …, 2020 - nature.com
Epithelial cell monolayers show remarkable displacement and velocity correlations over
distances of ten or more cell sizes that are reminiscent of supercooled liquids and active …

Glassy dynamics in dense systems of active particles

L Berthier, E Flenner, G Szamel - The Journal of chemical physics, 2019 - pubs.aip.org
Despite the diversity of materials designated as active matter, virtually all active systems
undergo a form of dynamic arrest when crowding and activity compete, reminiscent of the …

Intermittent relaxation and avalanches in extremely persistent active matter

YE Keta, R Mandal, P Sollich, RL Jack, L Berthier - Soft Matter, 2023 - pubs.rsc.org
We use numerical simulations to study the dynamics of dense assemblies of self-propelled

The nonequilibrium glassy dynamics of self-propelled particles

E Flenner, G Szamel, L Berthier - Soft matter, 2016 - pubs.rsc.org
We study the glassy dynamics taking place in dense assemblies of athermal active particles
