Imaging the emergence of bacterial turbulence: phase diagram and transition kinetics
Yi Peng, Zhengyang Liu, Xiang Cheng
We experimentally study the emergence of collective bacterial swimming, a phenomenon often referred to as bacterial turbulence. A phase diagram of the flow of 3D E. coli suspension…
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…
Dynamics of ellipsoidal tracers in swimming algal suspensions
Ou Yang, Yi Peng, Zhengyang Liu +3
Enhanced diffusion of passive tracers immersed in active fluids is a universal feature of active fluids and has been extensively studied in recent years. Similar to microrheology f…
Diffusion of an ellipsoid in bacterial suspensions
Yi Peng, Lipeng Lai, Yi-Shu Tai +3
Active matter such as swarming bacteria and motile colloids exhibits exotic properties different from conventional equilibrium materials. Among these properties, the enhanced diffu…
