The 2019 Motile Active Matter Roadmap
Gerhard Gompper, Roland G. Winkler, Thomas Speck +34
Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of active matter in recent years, which focuses on the physical…
Activity induced nematic order in isotropic liquid crystals
Sreejith Santhosh, Mehrana R. Nejad, Amin Doostmohammadi +2
We use linear stability analysis to show that an isotropic phase of elongated particles with dipolar flow fields can develop nematic order as a result of their activity. We argue t…
Mesoscale modelling of polymer aggregate digestion
Javor K. Novev, Amin Doostmohammadi, Andreas Zöttl +1
We use mesoscale simulations to gain insight into the digestion of biopolymers by studying the break-up dynamics of polymer aggregates (boluses) bound by physical cross-links. We i…
Active nematics with anisotropic friction: the decisive role of the flow aligning parameter
Kristian Thijssen, Luuk Metselaar, Julia M. Yeomans +1
We use continuum simulations to study the impact of anisotropic hydrodynamic friction on the emergent flows of active nematics. We show that, depending on whether the active partic…
Topology and morphology of self-deforming active shells
Luuk Metselaar, Julia M. Yeomans, Amin Doostmohammadi
We present a generic framework for modelling three-dimensional deformable shells of active matter that captures the orientational dynamics of the active particles and hydrodynamic…
Active Matter Invasion
Felix Kempf, Romain Mueller, Erwin Frey +2
Biological active materials such as bacterial biofilms and eukaryotic cells thrive in confined micro-spaces. Here, we show through numerical simulations that confinement can serve…
Reconfigurable Flows and Defect Landscape of Confined Active Nematics
Jérôme Hardoüin, Rian Hughes, Amin Doostmohammadi +5
Using novel micro-printing techniques, we develop a versatile experimental setup that allows us to study how lateral confinement tames the active flows and defect properties of the…
Active transport in a channel: stabilisation by flow or thermodynamics
Santhan Chandragiri, Amin Doostmohammadi, Julia M Yeomans +1
Recent experiments on active materials, such as dense bacterial suspensions and microtubule-kinesin motor mixtures, show a promising potential for achieving self-sustained flows. H…
