Collective self-optimization of communicating active particles
Alexandra V. Zampetaki, Benno Liebchen, Alexei V. Ivlev +1
The quest on how to collectively self-organize in order to maximize the survival chances of the members of a social group requires finding an optimal compromise between maximizing…
Dynamics of active particles with space-dependent swim velocity
Lorenzo Caprini, Umberto Marini Bettolo Marconi, René Wittmann +1
We study the dynamical properties of an active particle subject to a swimming speed explicitly depending on the particle position. The oscillating spatial profile of the swim veloc…
Anomalous cooling and overcooling of active systems
Fabian Jan Schwarzendahl, Hartmut Löwen
The phenomenon that a system at a hot temperature cools faster than at a warm temperature, referred to as the Mpemba effect, has been recently realized for trapped colloids. Here,…
Topology of orientational defects in confined smectic liquid crystals
Paul A. Monderkamp, René Wittmann, Louis B. G. Cortes +3
We propose a general formalism to characterize orientational frustration of smectic liquid crystals in confinement by interpreting the emerging networks of grain boundaries as obje…
Active droploids
Jens Grauer, Falko Schmidt, Jesus Pineda +4
Active matter comprises self-driven units, such as bacteria and synthetic microswimmers, that can spontaneously form complex patterns and assemble into functional microdevices. The…
Active Ornstein-Uhlenbeck model for self-propelled particles with inertia
G. H. Philipp Nguyen, René Wittmann, Hartmut Löwen
Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized…
