Linear and nonlinear active microrheology of viscous, viscoelastic, and elastic media: A fluid particle dynamics approach
Muhammed Muhsin Abdul Azeez, Henning Reinken, Andreas M. Menzel
Active microrheology is an effective tool to determine the rheological properties of viscous, viscoelastic, or elastic materials on microscopic length scales. The positional respon…
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…
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…
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…
Vortex pattern stabilization in thin films resulting from shear thickening of active suspensions
Henning Reinken, Andreas M. Menzel
The need for structuring on micrometer scales is abundant, for example, in view of phononic applications. We here outline a novel approach based on the phenomenon of active turbule…
Pattern selection and the route to turbulence in incompressible polar active fluids
Henning Reinken, Sebastian Heidenreich, Markus Bär +1
Active fluids, such as suspensions of microswimmers, are known to self-organize into complex spatio-temporal flow patterns. An intriguing example is mesoscale turbulence, a state o…
Optimal Turbulent Transport in Microswimmer Suspensions
Henning Reinken, Sabine H. L. Klapp, Michael Wilczek
Microswimmer suspensions self-organize into complex spatio-temporal flow patterns, including vortex lattices and mesoscale turbulence. Here we explore the consequences for the moti…
Ising-like critical behavior of vortex lattices in an active fluid
Henning Reinken, Sebastian Heidenreich, Markus Bär +1
Turbulent vortex structures emerging in bacterial active fluids can be organized into regular vortex lattices by weak geometrical constraints such as obstacles. Here we show, using…
Asymmetric pattern formation in microswimmer suspensions induced by orienting fields
Henning Reinken, Sebastian Heidenreich, Markus Bär +1
This paper studies the influence of orienting external fields on pattern formation, particularly mesoscale turbulence, in microswimmer suspensions. To this end, we apply a hydrodyn…
Derivation of a hydrodynamic theory for mesoscale dynamics in microswimmer suspensions
Henning Reinken, Sabine H. L. Klapp, Markus Bär +1
In this paper we systematically derive a fourth-order continuum theory capable of reproducing mesoscale turbulence in a three-dimensional suspension of microswimmers. We start from…
