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…

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…

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…
