Superdiffusivity of asymmetric exclusion process in dimensions one and two

C. Landim, J. Quastel, M. Salmhofer +1

We prove that the diffusion coefficient for the asymmetric exclusion process diverges at least as fast as $t^{1/4}$ in dimension $d=1$ and $(\log t{)}^{1/2}$ in $d=2$. The method app…
