报告摘要:

The first part of the talk focuses on the mechanical principle that a single bacterium uses to propel itself. We show that though widely-accepted resistive-force theory qualitatively describes the underlying principle of zero Reynolds number propulsion, it fails quantitatively in the biologically relevant regime due to the negligence of hydrodynamic interactions. In the second part, I will discuss a range of emerging phenomena observed in experimental systems consisting of many bacteria. These phenomena originate from interactions between self-propelled organisms; they include dynamic clusters, anomalous density fluctuation, scale-invariant correlation, and turbulence-like flow pattern.
