Critical dynamics of non-conserved strongly anisotropic permutation symmetric three-vector model

Abstract

We explore, employing the renormalization-group theory, the critical scaling behavior of the permutation symmetric three-vector model that obeys non-conserving dynamics and has a relevant anisotropic perturbation which drives the system into a non-equilibrium steady state. We explicitly find the independent critical exponents with corrections up to two loops. They include the static exponents $\nu$ and $\eta$, the off equilibrium exponent $\tilde{\eta }$, the dynamic exponent $z$ and the strong anisotropy exponent $\Delta$. We also express the other anisotropy exponents in terms of these.
