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.
