SUMMARY:Heinrich Jaeger, University of Chicago
DESCRIPTION:Granular Streams  Hosted by: Vivek Sharma    Abstract:  Streams of accelerated particles are important tools for probing atomic or molecular collision processes. In this talk I will show how particle streams also offer unique opportunities to investigate interactions in granular media, where the particles are much more macroscopic. Motivated by experiments on dense jets of particles that exhibit liquid-like breakup into droplets, we developed an experiment to investigate the evolution of a stream of granular media accelerated by gravity. This has opened up possibilities to resolve minute inter-particle forces and gain direct access to dynamic collision processes at the single particle level. The results have provided a host of new insights into the fundamental processes by which athermal particle aggregates break apart, they have revised our understanding of the origin of collisional charging in dielectrics, and they have provided a first glimpse at the creation of ?granular molecules? from individual particles via collide-and-capture events. | Event post: https://che.uic.edu/events?page_id=1075
