Sc. Park et al., Two-point correlation functions of the diffusion-limited annihilation in one dimension - art. no. 057102, PHYS REV E, 6305(5), 2001, pp. 7102
Two-point density-density correlation functions for the diffusive binary re
action system A+A--> empty set are obtained in one dimension via Monte Carl
o simulation. The long-time behavior of these correlation functions clearly
deviates from that of a recent analytical prediction of Bares and Mobilia
[Phys. Rev. Lett. 83, 5214 (1999)]. An alternative expression for the asymp
totic behavior is conjectured from numerical data.
