Abstract The study and classification of phase transitions is of major importance because it allows us to organize different systems according to theirmost basic features into universality classes. Phase transitions in nonequilibrium models have attracted recent attention, and here we are interested in continuous phase transition between absorbing and active nonequilibrium steady states. Such phase transitions are expected in many phenomena including turbulence, epidemic propagation and population dynamics.However, real experimental systems are not pure, they may contain impurities, defects and spatial inhomogeneities. Moreover, their parametersmay change with time. Even the least amounts of such spatial or temporal disorder can drastically affect the phase transition leading to new exoticbehavior. Hence, the presence of disorder is of great importance when describing real systems. While the effects of spatial disorder have been studied in some detail, the effects of temporal disorder are largely unexplored. In this project we therefore propose the investigation of nonequilibrium phase transitions with temporal disorder. Our methods will include large-scaleMonte Carlo simulations and renormalization group calculations. | |
