Universality and Scaling in Short-Time Critical Dynamics

For a statistical system in equilibrium (long time regime), the spatial correlation
length diverges at the critical temperature. The microscopic details are not
important and a universal behavior appears, characterized by the critical exponents.
The determination of critical exponents has long been one of the main interests for
both analytical and numerical calculations.

Is there any universal behavior in the short-time regime of the dynamic evolution?
The traditional answer is no, but this has been changed during the last years. In
fact, it has been shown that universality and scaling behavior are already present
in the dynamic system since the early stages of their dynamic evolution.

Here we review the finite size form for the scaling relations of the magnetization
and present results for dynamic and static exponents from Monte Carlo simulations.
