The 2024 Motile Active Matter Roadmap
Gerhard Gompper, Howard A. Stone, Christina Kurzthaler +29
Activity and autonomous motion are fundamental aspects of many living and engineering systems. Here, the scale of biological agents covers a wide range, from nanomotors, cytoskelet…
Frustrated run and tumble of swimming E-coli bacteria in nematic liquid crystals
Martyna Goral, Eric Clement, Thierry Darnige +2
In many situations bacteria move in complex environments, as for example in soils, oceans or the human gut-track microbiome. In these natural environments, carrier fluids such as m…
Run-to-Tumble Variability Controls the Surface Residence Times of Bacteria
Gaspard Junot, Thierry Darnige, Anke Lindner +6
Motile bacteria are known to accumulate at surfaces, eventually leading to changes in bacterial motility and bio-film formation. We use a novel two-colour, three-dimensional Lagran…
Optimised hyperbolic microchannels for the mechanical characterisation of bio-particles
Yanan Liu, Konstantinos Zografos, Joana Fidalgo +8
The transport of bio-particles in viscous flows exhibits a rich variety of dynamical behaviour, such as morphological transitions, complex orientation dynamics or deformations. Cha…
Lagrangian 3D tracking of fluorescent microscopic objects in motion
T. Darnige, N. Figueroa-Morales, P. Bohec +2
We describe the development of a tracking device, mounted on an epi-fluorescent inverted microscope, suited to obtain time resolved 3D Lagrangian tracks of fluorescent passive or a…
Spatial repartition of local plastic processes in different creep regimes in a granular material
A Pons, T Darnige, Jérôme Crassous +2
Granular packings under constant shear stress display below the Coulomb limit, a logarithmic creep dynamics. However the addition of small stress modulations induces a linear creep…
Mechanical fluctuations suppress the threshold of soft-glassy solids : the secular drift scenario
Adeline Pons, Axelle Amon, Thierry Darnige +2
We propose a dynamical mechanism leading to the fluidization of soft-glassy amorphous mate-rial driven below the yield-stress by external mechanical fluctuations. The model is base…
Creep and fluidity of a real granular packing near jamming
Van Bau Nguyen, Thierry Darnige, Ary Bruand +1
We study the internal dynamical processes taking place in a granular packing below yield stress. At all packing fractions and down to vanishingly low applied shear, a logarithmic c…
