Deformations of an active liquid droplet
Reiner Kree, Annette Zippelius
A fluid droplet in general deforms, if subject to active driving, such as a finite slip velocity or active tractions on its interface. We show that these deformations and their dyn…
From viscous fluids to elastic solids: A perspective on the glass transition
Annette Zippelius, Matthias Fuchs
A theory for the non-local stress in liquids captures the crossover from viscous to elastic correlations upon supercooling. It explains the emergence of long-ranged stress fields i…
Simple fluid with broken time reversal invariance
Niklas Grimm, Annette Zippelius, Matthias Fuchs
We characterize a system of hard spheres with a simple collision rule that breaks time reversal symmetry, but conserves energy. The collisions lead to an a-chiral, isotropic, and h…
Dynamics of bacteria scanning a porous environment
Ehsan Irani, Zahra Mokhtari, Annette Zippelius
It has recently been reported that bacteria, such as E.coli and P. putida, perform distinct modes of motion when placed in porous media as compared to dilute regions or free space.…
Dynamics of a droplet driven by an internal active device
Reiner Kree, Leon Rueckert, Annette Zippelius
A liquid droplet, immersed into a Newtonian fluid, can be propelled solely by internal flow. In a simple model, this flow is generated by a collection of point forces, which repres…
Chaos and mixing in self-propelled droplets
Reiner Kree, Annette Zippelius
We consider self-propelled droplets which are driven by internal flow. Tracer particles, which are advected by the flow, in general follow chaotic trajectories, even though the mot…
