Query: Cluster mean-field approximations with the coherent-anomaly-method
  analysis for the driven pair contact process with diffusion   The cluster mean-field approximations are performed, up to 13 cluster sizes,
to study the critical behavior of the driven pair contact process with
diffusion (DPCPD) and its precedent, the PCPD in one dimension. Critical points
are estimated by extrapolating our data to the infinite cluster size limit,
which are in good accordance with recent simulation results. Within the cluster
mean-field approximation scheme, the PCPD and the DPCPD share the same
mean-field critical behavior. The application of the coherent anomaly method,
however, shows that the two models develop different coherent anomalies, which
lead to different true critical scaling. The values of the critical exponents
for the particle density, the pair density, the correlation length, and the
relaxation time are fairly well estimated for the DPCPD. These results support
and complement our recent simulation results for the DPCPD.
