Query: Deterministic Equations of Motion and Phase Ordering Dynamics   We numerically solve microscopic deterministic equations of motion for the 2D
$\phi^4$ theory with random initial states. Phase ordering dynamics is
investigated. Dynamic scaling is found and it is dominated by a fixed point
corresponding to the minimum energy of random initial states.
