We present a class of ? ?two-dimensional randomized plaquette models, where the multi-spin ? ?interaction term, known as the plaquette term, is replaced by a ? ?single-site spin term with a probability p. By varying p, we observe ? ?a ground state phase transition at zero temperature, or ? ?equivalently, a phase transition of the symmetry operator. We find ? ?that as p changes, the symmetry operator transitions from being ? ?extensive to being localized in space. These models can be ? ?equivalently understood as 1+1D randomized cellular automaton ? ?dynamics, allowing the 2D transition to be interpreted as a 1+1D ? ?dynamical absorbing phase transition. Additionally, we discuss the ? ?connection between these models and the 1+1D measurement-induced ? ?entanglement phase transitions when the plaquette involves a 5-body interaction.
