AI总结:

本文研究了欧几里得引力路径积分中复度量的可接受性,发现黑洞鞍点在统计描述失效处违反KSW标准,并与两组分“灰星系”相变相关。

摘要:

欧几里得引力路径积分在黑洞物理的量子领域中证明了其显著的有效性。在本文中,我们考察了Kontsevich-Segal-Witten(KSW)标准在欧几里得引力路径积分中对可接受复度量的应用性。我们发现,对于具有不等角动量的${\cal N}=4$ SYM超对称索引,黑洞鞍点恰好在统计描述失效的地方违反KSW标准。相应的临界点与微正则集合中向两组分“灰星系”配置的相变相吻合。

英文摘要:

The Euclidean Gravitational Path Integral has proven remarkably effective in the quantum regime of black hole physics. In this work, we examine the applicability of the Kontsevich-Segal-Witten (KSW) criterion for admissible complex metrics in the context of the Euclidean Gravitational Path Integral. We find that, for the super-conformal index of ${\cal N}=4$ SYM with unequal angular momenta, the black hole saddle points violate the KSW criterion precisely where the statistical description of the index breaks down. The corresponding critical point coincides with a phase transition into two-component ``grey galaxy'' configurations in the micro-canonical ensemble.
