  4. Abstract:
  5. A non-Markovian generalization of a one-dimensional contact process is being introduced in which every particle has an age and will be annihilated at its maximum age τ. There is an absorbing state phase transition which is controlled by this parameter. The model can demonstrate oscillatory behavior in its approach to the stationary state. These oscillations are also present in the mean-field approximation, which is a first-order differential equation with time delay. Studying dynamical critical exponents suggests that the model belongs to the direct percolation universality class. © 2002 The American Physical Society
