Topological signatures of collective dynamics and turbulent-like energy cascades in apolar active granular
Zihan Zheng, Cunyuan Jiang, Yangrui Chen +2
Active matter refers to a broad class of non-equilibrium systems where energy is continuously injected at the level of individual ``particles". These systems exhibit emergent colle…

Power Spectra of Velocity Fluctuations in Granular Heap Flow
ShuChang Yu, Jin Shang, YangRui Chen +5
This study used Speckle Visibility Spectroscopy to examine velocity fluctuations in a three-dimensional granular heap flow, where the mean velocity profile consists of a fast-flow…

Experimental observation of gapped shear waves and liquid-like to gas-like dynamical crossover in active granular matter
Cunyuan Jiang, Zihan Zheng, Yangrui Chen +2
Unlike crystalline solids, liquids lack long-range order, resulting in diffusive shear fluctuations rather than propagating waves. Simulations predict that liquids exhibit a -ga…
