Exploring the enigmatic behavior of granular materials through sound

Los Angeles CA (SPX) Apr 19, 2024

Granular materials, such as coffee beans in a jar or piles of sand, are composed of macroscopic particles and represent a significant yet little understood frontier in fundamental physics. Recent studies, including one in the European Physical Journal E by Onuttom Narayan and Harsh Mathur, focus on how sound moves through these materials, especially near the jamming transition. This phenom
