Hydrodynamics substantially affects induced structure formation in magnetic fluids
Henning Reinken, Markus Heiber, Takeaki Araki +1
Magnetorheological fluids consist of micrometer-sized magnetic particles in a carrier liquid. Sufficiently strong external magnetic fields lead to the formation of string-like part…
Rheologically tuned modes of collective transport in active viscoelastic films
Henning Reinken, Andreas M. Menzel
While many living biological media combine both viscous and elastic properties, most theoretical studies employ either purely fluid- or solid-like descriptions. We here use a unifi…
Unified description of viscous, viscoelastic, or elastic thin active films on substrates
Henning Reinken, Andreas M. Menzel
It is frequent for active or living entities to find themselves embedded in a surrounding medium. Resulting composite systems are usually classified as either active fluids or acti…
Self-sustained patchy turbulence in shear-thinning active fluids
Henning Reinken, Andreas M. Menzel
Bacterial suspensions and other active fluids are known to develop highly dynamical vortex states, denoted as active or mesoscale turbulence. We reveal the pronounced effect of non…
Oscillatory collective motion in viscoelastic and elastic active fluids and solids under circular confinement
Henning Reinken, Andreas M. Menzel
In an inspiring recent study, Xu et al. [Nat. Phys. 19, 46 (2023)] observed for a living active biofilm under circular confinement two emergent dynamic modes of collective motion i…
