Simulations and theory are being used to investigate the statistical mechanics of jammed particulate matter. JAMMED MATTER A slow shear flow is a applied to a jammed system of grains. Mobility and diffusivity measurements yield an effective temperature which is indeed very close to that obtained using a statistical ensemble of jammed configurations.

The network formed by the jammed configurations and their transition states is a “small-world” network with a scale-invariant topology. Each node in the network is a jammed state. The nodes are linked if there is transition state between them. The network has the same topological properties as other complex networks such as WWW, Internet, protein- protein interaction networks, and sociological networks.

Education Students: two graduate students and four undergraduate students. International collaborations: one exchange student from Fortaleza, Brazil, and one from ENS, France. International collaborations with Prof. Shlomo Havlin (Israel), Dr. Jorge Kurchan, (Paris) and Prof. Sam Edwards (UK). Attraction and retention of minority students: 3 undergraduate minority students working in the lab from Physics, Chemical and Mechanical Engineering reflecting the interdisciplinary nature of our work. Dissemination to a broader audience: Why does this Translation of the web content to spanish “Porque algunas areniscas presentan franjas?” At: http://www.seed.slb.com/es/index.htm Curriculum development: New graduate course: Granular Matter. Students are introduced to research earlier in their careers: a student project comparing experiments and simulation of sandpiles has been recently published in J. Stat. Phys. 3, 1-8 (2004). sandstone from Petra have stripes?
