摘要：

We study the decay of the probability for a non-Markovian stationary Gaussian walker not to cross the origin up to time t. This result is then used to evaluate the fraction of spins that do not flip up to time t in the zero temperature Monte Carlo spin flip dynamics of the Ising model. Our results are compared to extensive numerical simulations.
