Bacterial turbulence at compressible fluid interfaces
Yuanfeng Yin, Bokai Zhang, H. P. Zhang +1
Dense bacterial suspensions at fluid interfaces provide a natural platform to explore active turbulence in a dimensional mismatch: active units are restricted to a two-dimensional…

Transport and Energetics of Bacterial Rectification
Satyam Anand, Xiaolei Ma, Shuo Guo +2
Randomly moving active particles can be herded into directed motion by asymmetric geometric structures. Although such a rectification process has been extensively studied due to it…

Symmetric shear banding and swarming vortices in bacterial "superfluids"
Shuo Guo, Devranjan Samanta, Yi Peng +2
Bacterial suspensions--a premier example of active fluids--show an unusual response to shear stresses. Instead of increasing the viscosity of the suspending fluid, the emergent col…
