Density Fluctuations and Energy Spectra of 3D Bacterial Suspensions
Zhengyang Liu, Wei Zeng, Xiaolei Ma +1
We experimentally study density fluctuations and energy spectra of bulk \textit{E. coli} suspensions of different concentrations. Our results verify the predicted scaling law of gi…
Experimental investigations on the nonequilibrium dynamics of pattern formation in fluid and granular systems
Xiaolei Ma
Patterns are quotidian in nature. Distinct multiscale patterns are generally a consequence of nonequilibrium dynamical processes associated with mechanical or hydrodynamic instabil…
Universal Scaling of Polygonal Desiccation Crack Patterns
Xiaolei Ma, Janna Lowensohn, Justin C. Burton
Polygonal desiccation crack patterns are commonly observed in natural systems. Despite their quotidian nature, it is unclear whether similar crack patterns which span orders of mag…
Self-organized oscillations of Leidenfrost drops
Xiaolei Ma, Justin C. Burton
In the Leidenfrost effect, a thin layer of evaporated vapor forms between a liquid and a hot solid. The complex interactions between the solid, liquid, and vapor phases can lead to…
