Numerical evidence of Janssen-Oerding's prediction in a three-dimensional spin model far from equilibrium

Abstract

In 1994, Jansen and Oerding predicted an interesting anomalous tricritical dynamic behavior in threedimensional models via renormalization group theory. However, we highlight the lack of literature about the computational verification of this universal behavior. Here, we use some tricks to capture the log corrections and the parameters predicted by these authors using the three-dimensional Blume-Capel model. We quantify the crossover phenomena by computing the critical exponents near the tricritical point. In addition, we also perform a more detailed study of the dynamic localization of the phase diagram via power-law optimization.
