Random deposition of two annihilating species in the (1+1) dimension.
We present simulation results for the one-dimensional random deposition of two annihilating species A and B, falling with probabilities p and q (p+q=1), which then react to produce an inert product, i.e., A+B-->0. Two different annihilation rules are defined: top annihilation and nearest-neighbor annihilation (NNA), leading to distinct scaling behaviors. In particular, the values of the scaling exponents for NNA are found to be dependent on probability p, suggesting different universality classes.
