Discontinuous fluidisation transition in assemblies of actively-deforming particles: A new paradigm for collective motion in dense active materials
Elsen Tjhung, Ludovic Berthier
Tracking experiments in dense biological tissues reveal a diversity of sources f or local energy injection at the cell scale. The effect of cell motility has been largely studied,…
The nonequilibrium glassy dynamics of self-propelled particles
Elijah Flenner, Grzegorz Szamel, Ludovic Berthier
We study the glassy dynamics taking place in dense assemblies of athermal active particles that are driven solely by a nonequilibrium self-propulsion mechanism. Active forces are m…
Ultra-long-range dynamic correlations in a microscopic model for aging gels
Pinaki Chaudhuri, Ludovic Berthier
We use large-scale computer simulations to explore the non-equilibrium aging dynamics in a microscopic model for colloidal gels. We find that gelation resulting from a kinetically-…
