具有立方相互作用的五维O(N)模型的非微扰RG分析

Nonperturbative RG analysis of five-dimensional O(N) models with cubic interactions

Kazuhiko Kamikado, Takuya Kanazawa

摘要:

利用泛函重整化群方程重新考虑了$d>4$维具有立方相互作用的O(N)标量模型的临界性质。工作在下一个领导阶的衍生物的扩展,我们发现非平凡的IR不动点在小和中间N从β函数的相关立方项。本文还讨论了最近由高自旋全息和ε展开提出的大N时的假定不动点,并着重讨论了有效势的稳定性。

英文摘要:

We reconsider critical properties of O(N) scalar models with cubic interactions in $d>4$ dimensions using functional renormalization group equations. Working at next-to-leading order in the derivative expansion, we find non-trivial IR fixed points at small and intermediate N from beta functions for relevant cubic terms. The putative fixed point at large N suggested recently by higher spin holography and the epsilon-expansion is also discussed, with an emphasis on stability of the effective potential.
