This article investigates the nonequilibrium critical behavior of the contact process with deterministic aperiodic temporal disorder. The authors test the generalized criterion in the mean-field limit using analytic and numerical calculations.
We investigate the nonequilibrium critical behavior of the contact process with deterministic aperiodic temporal disorder implemented by choosing healing or infection rates according to a family of aperiodic sequences based on the quasiperiodic Fibonacci sequence. This family allows us to gauge the temporal fluctuations via a wandering exponent cv and put our work in the context of the Kinzel-Vojta-Dickman criterion for the relevance of temporal disorder to the critical behavior of nonequilibrium models. By means of analytic and numerical calculations, the generalized criterion is tested in the mean-field limit.
