AI总结:

本文利用 DHS 公式在完整黑洞背景下推导了近极端旋转 BTZ 黑洞配分函数的 $T^{3/2}$ 标度,并推导任意自旋场谱测度以给出新证明,为证明 4d Kerr 黑洞标度指明路径。

摘要:

近期关于近极端非超对称黑洞量子力学的研究,发现了低温黑洞配分函数具有特征性的 $T^{3/2}$ 标度。该结果仅通过近视界区域的路径积分推导得出,并依赖于诸多假设。我们探讨了如何使用 Denef-Hartnoll-Sachdev (DHS) 公式,在完整黑洞背景下进行计算,从而推导近极端旋转 BTZ 黑洞的 $T^{3/2}$ 标度;该公式将热几何的 1-圈行列式表示为似正模谱的乘积。我们还推导了欧几里得 BTZ 中任意自旋场的谱测度,并以此提供 DHS 公式的新证明,以及 BTZ 热核的全新直接推导。这些计算为证明渐近平坦 4d Kerr 黑洞的 $T^{3/2}$ 标度指明了路径。

英文摘要:

Recent work on the quantum mechanics of near-extremal non-supersymmetric black holes has identified a characteristic $T^{3/2}$ scaling of the low temperature black hole partition function. This result has only been derived using the path integral in the near-horizon region and relies on many assumptions. We discuss how to derive the $T^{3/2}$ scaling for the near-extremal rotating BTZ black hole from a calculation in the full black hole background using the Denef-Hartnoll-Sachdev (DHS) formula, which expresses the 1-loop determinant of a thermal geometry in terms of a product over the quasinormal mode spectrum. We also derive the spectral measure for fields of any spin in Euclidean BTZ and use it to provide a new proof of the DHS formula and a new, direct derivation of the BTZ heat kernel. The computations suggest a path to proving the $T^{3/2}$ scaling for the asymptotically flat 4d Kerr black hole.
