Differential-activity driven instabilities in biphasic active matter
Christoph Weber, Chris H. Rycroft, L. Mahadevan
Active stresses can cause instabilities in contractile gels and living tissues. Here we describe a generic hydrodynamic theory that treats these systems as a mixture of two phases…
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…
Droplet Ripening in Concentration Gradients
Christoph A. Weber, Chiu Fan Lee, Frank Jülicher
Living cells use phase separation and concentration gradients to organize chemical compartments in space. Here, we present a theoretical study of droplet dynamics in gradient syste…
Pili mediated intercellular forces shape heterogeneous bacterial microcolonies prior to multicellular differentiation
Wolfram Pönisch, Kelly Eckenrode, Khaled Alzurqa +4
Microcolonies are aggregates of a few dozen to a few thousand cells exhibited by many bacteria. The formation of microcolonies is a crucial step towards the formation of more matur…
