Abstract

Bacterial swarming is a collective mode of motion in which cells migrate rapidly over surfaces. Swarming is typically characterized by densely packed groups moving in coherent patterns of whirls and flows. Recent experiments showed that within such dense swarms, bacteria are performing super-diffusion that is consistent with a Levy walk. The talk will explain this observation and present a simple model suggesting that chaos and Levy walking are a consequence of group dynamics. The model explains how cells can fine-tune the geometric properties of their trajectories.
