论文摘要
我们探索采用重新归一化的组理论，即遵守对称的三矢量模型的临界缩放行为，该模型遵守非连接动力学，并具有相关的各向异性扰动，该动力扰动将系统驱动到非平衡稳态。我们明确地找到具有最多两个循环的独立关键指数。它们包括静态指数$ν$和$η$，OFF平衡指数$ \widetildeη$，动态指数$ z $和强方差指数$δ$。我们还根据这些表达其他各向异性指数。
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 $ν$ and $η$, the off equilibrium exponent $\widetildeη$, the dynamic exponent $z$ and the strong anisotropy exponent $Δ$. We also express the other anisotropy exponents in terms of these.
