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…
Active-passive mixtures with bulk loading: a minimal active engine in one dimension
Jean-François Derivaux, Robert L. Jack, Michael E. Cates
We study a one-dimensional mixture of active (run-and-tumble) particles and passive (Brownian) particles, with single-file constraint, in a sawtooth potential. The active particles…
Competition between lanes and transient jammed clusters in driven binary mixtures
Honghao Yu, Robert L. Jack
We consider mixtures of oppositely driven particles, showing that their non-equilibrium steady states form lanes parallel to the drive, which coexist with transient jammed clusters…
Necking and failure of a colloidal gel arm: signatures of yielding on different length scales
Kristian Thijssen, T. B. Liverpool, C. Patrick Royall +1
Colloidal gels consist of percolating networks of interconnected arms. Their mechanical properties depend on the individual arms, and on their collective behaviour. We use numerica…
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…
Tricritical behavior in dynamical phase transitions
Tal Agranov, Michael E. Cates, Robert L. Jack
We identify a new scenario for dynamical phase transitions associated with time-integrated observables occurring in diffusive systems described by the macroscopic fluctuation theor…
