Comparison inequality and two block estimate for inhomogeneous Bernoulli measures

Jeremy Quastel

We consider inhomogeneous Bernoulli measures of the form $\prod_{x \in Λ} p_{x}$ where $p_{x}$ are prescribed and uniformly bounded above and below away from 0 and 1. A comparison inequa…

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 $(lo g t)^{1/2}$ in $d = 2$ . The method app…
