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…
Dispersionless Flat Mode and Vibrational Anomaly in Active Brownian Vibrators Induced by String-like Dynamical Defects
Cunyuan Jiang, Zihan Zheng, Yangrui Chen +2
In recent years, active Brownian particles have emerged as a prominent model system for comprehending the behaviors of active matter, wherein particles demonstrate self-propelled m…
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…
Disorder-induced vibrational anomalies from crystalline to amorphous solids
Ling Zhang, Yinqiao Wang, Yangrui Chen +8
The origin of boson peak -- an excess of density of states over Debye's model in glassy solids -- is still under intense debate, among which some theories and experiments suggest t…
Critical behaviors of jamming in cyclically sheared frictional hard granular particles
Aile Sun, Yinqiao Wang, Yangrui Chen +5
In stark contrast to the jamming of frictionless hard-sphere (hard-disk if in two dimensions) packings, the critical jamming of frictional packings is much more elusive and still u…
