Abstract
Using molecular dynamics computer simulations we investigate the structural and dynamical properties of a simple model for a colloidal gel at low volume fraction. We find that at low T the system is forming an open percolating cluster, without any sign of a phase separation. The nature of the relaxation dynamics depends strongly on the length scale/wave-vector considered and can be directly related to the geometrical properties of the spanning cluster.Keywords
