Journal: | Physical Review E | Abstract: | Nonequilibrium critical phenomena generally exist in many dynamic systems, like chemical reactions and some driven-dissipative reactive particle systems. Here, by using computer simulation and theoretical analysis, we demonstrate the crucial role of the activation barrier on the criticality of dynamic phase transitions in a minimal reactive hard-sphere model. We find that at zero thermal noise, with increasing the activation barrier, the type of transition changes from a continuous conserved directed percolation into a discontinuous dynamic transition by crossing a tricritical point. A mean-field theory combined with field simulation is proposed to explain this phenomenon. The possibility of Ising-type criticality in the nonequilibrium system at finite thermal noise is also discussed. | URI: | https://hdl.handle.net/10356/154970 | ISSN: | 2470-0045 | DOI: | 10.1103/PhysRevE.103.052607 | Schools: | School of Chemical and Biomedical Engineering | Rights: | © 2021 American Physical Society.
