Title: Zero-temperature limit of  the Kawasaki dynamics for the Ising lattice gas in a large
  two-dimensional torus

Abstract: We consider the Kawasaki dynamics at inverse temperature $\beta$ for
  the Ising lattice gas on a two-dimensional square of length $2L+1$
  with periodic boundary conditions. We assume that initially the
  particles form a square of length $n$, which may increase, as well
  as $L$, with $\beta$. We show that in a proper time scale $L^2\,
  \theta_\beta$ particles form almost always a square and that this
  square evolves as a Brownian motion when the temperature vanishes.
