- Description
- We use Monte Carlo simulation to study new features of the (one-dimensional) Domany-Kinzel cellular automaton (CA). Considering the relaxation process of the "magnetization" (the frozen-active order parameter) towards its equilibrium value, we measure its dynamical critical exponent <math>z\,\!</math>. Also, We investigate the effect of <math>p_{0} \ne 0\,\!</math> (nonvanishing external field conjugate to the magnetization) on the phase diagram and on the susceptibility. Finally, we introduce constraints in the evolution rule of the Domany-Kinzel CA and study the associated criticality (critical surfaces and universality classes).
