论文摘要
$ O（n）$对称模型的多临界固定点不再存在于$ n \ to \ infty $限制中，但是调节其歼灭的机制仍然呈现出几个神秘的方面。在这里，我们探讨了$（d，n）$平面中高阶多临界点的演变，并以$ n $的渐近行为揭示了复杂的马赛克。这张照片通过各种RG方法证实，构成了对$ O（n）$ field理论中关键行为的完全理解的基本步骤。
The multi-critical fixed points of $O(N)$ symmetric models cease to exist in the $N\to\infty$ limit, but the mechanism regulating their annihilation still presents several enigmatic aspects. Here, we explore the evolution of high-order multi-critical points in the $(d,N)$ plane and uncover a complex mosaics for their asymptotic behaviour at large $N$. This picture is confirmed by various RG approaches and constitutes a fundamental step towards the full comprehension of critical behaviour in $O(N)$ field theories.
