In this work we study the one-dimensional contact process with diffusion using two different approaches to estimate the critical properties of this model: the supercritical series expansion and finite size exact solution approaches. We place special emphasis on looking at the multicritical point and its crossover exponent that characterizes the passage between directed percolation and mean-field critical properties. This crossover occurs in the limit of infinite diffusion rate and our results…

The phase diagrams of conservative diffusive contact processes are determined by means of numerical simulations and indicate that in the limit of infinite diffusion rate the jump in density equals 2/3 for the pair- creation model and 5/6 for the triplet-creation model.
