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.
