Instabilities and transport properties in sheared granular gases
By means of molecular dynamics simulations we investigated a two-dimensional system of sheared granular matter where we found an additional instability related to the well known clustering instability. We found that the symmetry of the initial condition determines where clustering occurs. Measuring velocity correlation functions as well as diffusion coefficients and their dependence on the restitution coefficient we present how this phenomenon is reflected in the transport properties of the system.
