Im currently looking into The asymmetric simple exclusion process. I am stuggling to understand the density and current within the model. From what I have researched the current depends on the density, $j=\gamma(1-\gamma)$. However I am not sure what both the density and current represent within the model? Many thanks in advance.

just too add I believe the density to be the probability of which each lattice is occupied independently and the current to be the flow of the lattice in question? –  user24930 Oct 10 '12 at 15:14
