TY - JOUR ID - teitel07 L3 - citeulike-article-id:2200075 N2 - We carry out numerical simulations to study transport behavior about the jamming transition of a model granular material in two dimensions at zero temperature. Shear viscosity is computed as a function of particle volume density and applied shear stress , for diffusively moving particles with a soft core interaction. We find an excellent scaling collapse of our data as a function of the scaling variable /|c-|, where c is the critical density at =0 (“point J”), and is the crossover scaling critical exponent. We define a correlation length from velocity correlations in the driven steady state and show that it diverges at point J. Our results support the assertion that jamming is a true second-order critical phenomenon.
