Formation of liquid shells in active droplet systems
Jonathan Bauermann, Giacomo Bartolucci, Job Boekhoven +2
We study a chemically active binary mixture undergoing phase separation and show that under non-equilibrium conditions, stable liquid spherical shells can form via a spinodal insta…
Physics of Active Emulsions
Christoph A. Weber, David Zwicker, Frank Jülicher +1
Phase separating systems that are maintained away from thermodynamic equilibrium via molecular processes represent a class of active systems, which we call active emulsions. These…
Discontinuous switching of position of two coexisting phases
Samuel Krüger, Christoph A. Weber, Jens-UweSommer +1
Here we investigate how the positions of a condensed phase can be controlled by using concentration gradients of a regulator that influences phase separation. We consider a mean fi…
Formation and Dissolution of Bacterial Colonies
Christoph Weber, Yen Ting Lin, Nicolas Biais +1
Many organisms form colonies for a transient period of time to withstand environmental pressure. Bacterial biofilms are a prototypical example of such behavior. Despite significant…
Binary Mixtures of Particles with Different Diffusivities Demix
Simon N. Weber, Christoph A. Weber, Erwin Frey
The influence of size differences, shape, mass and persistent motion on phase separation in binary mixtures has been intensively studied. Here we focus on the exclusive role of dif…
Numerical treatment of the Boltzmann equation for self-propelled particle systems
Florian Thüroff, Christoph A. Weber, Erwin Frey
Kinetic theories constitute one of the most promising tools to decipher the characteristic spatio-temporal dynamics in systems of actively propelled particles. In this context, the…
