Active screws: Emergent active chiral nematics of spinning self-propelled rods
Debarghya Banerjee, Lauritz Hahn, Ricard Alert
Several types of active agents self-propel by spinning around their propulsion axis, thus behaving as active screws. Examples include cytoskeletal filaments in gliding assays, magn…
Buckling by disordered growth
Rahul G. Ramachandran, Ricard Alert, Pierre A. Haas
Buckling instabilities driven by tissue growth underpin key developmental events such as the folding of the brain. Tissue growth is disordered due to cell-to-cell variability, but…
Dynamical arrest in active nematic turbulence
Ido Lavi, Ricard Alert, Jean-François Joanny +1
Active fluids display spontaneous turbulent-like flows known as active turbulence. Recent work revealed that these flows have universal features, independent of the material proper…
Nonlinear spontaneous flow instability in active nematics
Ido Lavi, Ricard Alert, Jean-François Joanny +1
Active nematics exhibit spontaneous flows through a well-known linear instability of the uniformly-aligned quiescent state. Here we show that even a linearly stable uniform state c…
Flocking by Turning Away
Suchismita Das, Matteo Ciarchi, Ziqi Zhou +3
Flocking, as paradigmatically exemplified by birds, is the coherent collective motion of active agents. As originally conceived, flocking emerges through alignment interactions bet…
