Self-organization, detailed balance, and stress-structure correlations in 2D granular dynamics
Raphael Blumenfeld, Takashi Matsushima, Jie Zhang
We argue that a number of recent experimental and numerical observations point to an ongoing cooperative stress-structure self-organisation (SO) in quasi-static granular dynamics.…
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…
Crystalline and polycrystalline regimes in a periodically sheared 2-dimensional system of disks
Siyuan Su, Jie Zhang, Charles Radin +1
A layer of monodisperse circular steel disks in a nearly square horizontal cell forms, for shear amplitudes SA 0.08, hexagonal close-packed crystallites that grow and merge u…
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…
Spatiotemporal Chaotic unjamming and jamming in granular avalanches
Ziwei Wang, Jie Zhang
We have investigated the spatiotemporal chaotic dynamics of unjamming and jamming of particles in a toy-model system -- a rotating drum partially filled with bidisperse disks to cr…
