TL;DR
This paper investigates the metastable behavior of a two-state probabilistic cellular automaton with self-interaction, revealing competing metastable states and similarities to the Blume-Capel model.
Contribution
It introduces a novel analysis of metastability in a two-state automaton with self-interaction, highlighting the emergence of competing metastable states.
Findings
Competing metastable states depend on self-interaction strength
Behavior resembles the three-state Blume-Capel model
Metastability phenomena are characterized in the automaton
Abstract
Metastability is observed when a physical system is close to a first order phase transition. In this paper the metastable behavior of a two state reversible probabilistic cellular automaton with self-interaction is discussed. Depending on the self-interaction, competing metastable states arise and a behavior very similar to that of the three state Blume-Capel spin model is found.
