Explore the rheological behavior of dense granular materials through the lens of fluctuation dynamics in this 44-minute conference talk. Delve into the complex physics governing how granular matter transitions between solid-like and fluid-like states, examining how microscopic fluctuations influence macroscopic flow properties. Learn about cutting-edge research connecting soft matter physics principles to geophysical phenomena, including applications to understanding Earth materials like soil, mud, and rocks. Discover how fluctuation-based approaches provide new insights into the mechanical behavior of dense granular systems, with implications for predicting and modeling natural processes such as landslides, erosion, and other geological dynamics. Gain understanding of the theoretical frameworks and experimental approaches used to characterize granular rheology, including the role of particle interactions, stress transmission, and collective motion in determining material response under various loading conditions.
