摘要

Using Monte Carlo method with zero-temperature dynamics, we investigate energy evolution of Ising spin configuration on a square lattice.The energies of some configurations exhibit long duration before those configurations reach the final state -- ground state or frozen stripe state.For ground-state dynamical realization, the duration occurs when the energy per spin is 4/L, where L is the lattice size.For stripe-state dynamical realization, the energy is slightly higher than 2/ L when the duration appears in the last evolution stage.In addition, it is found that the average energy per spin in final state is approximately 2/3L.
