News From the Field

Of Traffic Jams, Beach Sands and the Zero-temperature Jamming Transition


May 13, 2009

chemistry and materials graphic Researchers at the University of Pennsylvania and the University of Chicago have created a model to better understand jamming. The study presents the first experimental evidence of a vestige of the zero temperature jamming transition--the density at which large, loose objects such as gas bubbles in liquid, grains of sand or cars become rigid solids such as foam, sand dunes or traffic jams--in a system of small particles where thermal energy is important.
