Biophysics underlying the swarm to biofilm transition
Vasco M. Worlitzer, Ajesh Jose, Ilana Grinberg +5
Bacteria organize in a variety of collective states, from swarming, which has been attributed to rapid surface exploration, to biofilms, which are highly dense immobile communities…
Turbulence-induced clustering in compressible active fluids
Vasco M. Worlitzer, Gil Ariel, Avraham Be'er +3
We study a novel phase of active polar fluids, which is characterized by the continuous creation and destruction of dense clusters due to self-sustained turbulence. This state aris…
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…
