Linear stability and viscoelastic response in weakly jammed frictional granular systems
Masanari Shimada, Yusuke Hara, Shihori Koyama +2
Granular particles typically feature contact friction, which gives rise to various nontrivial properties of granular materials. In this work, we investigate the linear stability of…
Enhanced collective vibrations in granular materials
Shihori Koyama, Norihiro Oyama, Hideyuki Mizuno +1
Granular materials are defined as collections of macroscopic dissipative particles. Although these systems are ubiquitous in our lives, the nature and the causes of their non-trivi…
Anomalous Diffusion in a Monolayer of Lightweight Spheres Fluidized in Airflow
Shihori Koyama, Tomoki Matsuno, Takashi Noguchi
This paper presents statistical analyses of random motions in a single layer of fluidized lightweight spherical particles. Foam polystyrene spheres were driven by an upward airflow…
