AI总结:

本文在张量场理论平均场分析中发现,由于组合非局域相互作用,有效质量在整个非零真空期望值相中消失,导致超越临界点的标度不变性涌现,并可能增强为共形不变性。

摘要:

我们继续系列文章的工作,应用朗道-金兹堡平均场理论揭示以组合非局域相互作用为特征的张量场理论的基本相结构。除其他外,这一类理论涵盖张量场理论(TFT),它引出一类新的共形场论,与 AdS/CFT 猜想的研究高度相关。此外,它还包括量子引力张量群场论(TGFT)方法中的模型。关键的是,在红外区我们发现,由于相互作用的非局域性,与临界行为相关的模式的有效质量不仅在临界点处消失,而且在整个非零真空期望值相中也消失。因此,在那里会遇到位形空间上标度不变性的涌现,并且该标度不变性有可能进一步增强为位形空间上的共形不变性。

英文摘要:

We continue the series of articles on the application of Landau-Ginzburg mean-field theory to unveil the basic phase structure of tensorial field theories which are characterized by combinatorially non-local interactions. Among others, this class covers tensor field theories (TFT) which lead to a new class of conformal field theories highly relevant for investigations on the AdS/CFT conjecture. Moreover, it also encompasses models within the tensorial group field theory (TGFT) approach to quantum gravity. Crucially, in the infrared we find that the effective mass of the modes relevant for the critical behavior vanishes not only at criticality but also throughout the entire phase of non-vanishing vacuum expectation value due to the non-locality of the interactions. As a consequence, one encounters there the emergence of scale invariance on configuration space which is potentially enhanced to conformal invariance thereon.
