Dynamical mean-field theory and weakly non-linear analysis for the phase separation of active Brownian particles
Thomas Speck, Andreas M. Menzel, Julian Bialké +1
Recently, we have derived an effective Cahn-Hilliard equation for the phase separation dynamics of active Brownian particles by performing a weakly non-linear analysis of the effec…
Negative interfacial tension in phase-separated active suspensions
Julian Bialké, Hartmut Löwen, Thomas Speck
We study numerically a model for active suspensions of self-propelled repulsive particles, for which a stable phase separation into a dilute and a dense phase is observed. We explo…
Dynamical clustering and phase separation in suspensions of self-propelled colloidal particles
Ivo Buttinoni, Julian Bialké, Felix Kümmel +3
We study experimentally and numerically a (quasi) two dimensional colloidal suspension of self-propelled spherical particles. The particles are carbon-coated Janus particles, which…
Crystallization in a dense suspension of self-propelled particles
Julian Bialké, Thomas Speck, Hartmut Löwen
Using Brownian dynamics computer simulations we show that a two-dimensional suspension of self-propelled ("active") colloidal particles crystallizes at sufficiently high densities.…
