摘要：

We study the effects of rapidly cooling to T=0 a spin chain with conserved dynamics and competing interactions. Depending on the degree of competition, the system:is:found to get arrested in different kinds of metastable states. The most interesting of these has an inhomogeneous mixture of interspersed active and quiescent regions. In this state, the steady-state autocorrelation :function decays as a stretched exponential similar to exp[-(t/t(0))(1/3)]. and there is a two-step relaxation to equilibrium when the temperature is raised slightly.
