Abstract

We study the one-dimensional contact process in its quantum version using a recently proposed real-space renormalization technique for stochastic many -particle systems. Exploiting the duality and other properties of the model , we can apply the method for cells with up to 37 sites. After suitable ext rapolation, we obtain exponent estimates that are comparable in accuracy wi th the best known in the literature.
