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…
Liquid-liquid phase transition in an atomistic model glass former
Thomas Speck, C. Patrick Royall, Stephen R. Williams
Whether the glass transition is caused by an underlying singularity or is a purely kinetic phenomenon is a significant outstanding question. Studying an atomistic glass former, we…
Active colloidal suspensions: Clustering and phase behavior
Julian Bialké, Thomas Speck, Hartmut Löwen
We review recent experimental, numerical, and analytical results on active suspensions of self-propelled colloidal beads moving in (quasi) two dimensions. Active colloids form part…
Meta-work and the analogous Jarzynski relation in ensembles of dynamical trajectories
Robert M. Turner, Thomas Speck, Juan P. Garrahan
Recently there has been growing interest in extending the thermodynamic method from static configurations to dynamical trajectories. In this approach, ensembles of trajectories are…
