一大类$D$维引力理论的球对称扇区可以有效地由一般的二维Horndeski理论描述。利用这一对应关系,我们通过推导出基于Jackiw--Teitelboim(JT)引力的普适近视界有效描述,研究了母理论中近极端黑洞解的低温动力学。我们明确证明,先前在爱因斯坦引力与物质耦合情形下,从单圈精确JT配分函数导出的近极端黑洞熵的对数量子修正$S_{\rm JT}=\frac{3}{2}\log \left(T/T_{\rm breakdown} \right)$,在所有允许有效二维Horndeski描述的模型中具有普适性。我们确定了该修正变得主导的尺度$T_{\rm breakdown}$的一般形式,用$D$维理论的数据表示。我们以Lovelock引力中的带电黑洞和Quasitopological引力中的正则黑洞为例,说明我们的普遍结果。
英文摘要
The spherically symmetric sector of broad classes of $D$-dimensional gravitational theories can be effectively described by general two-dimensional Horndeski theories. Exploiting this correspondence, we study the low-temperature dynamics of near-extremal black hole solutions of the parent theories by deriving a universal near-horizon effective description in terms of Jackiw--Teitelboim (JT) gravity. We explicitly show that the logarithmic quantum correction to the entropy, $S_{\rm JT}=\frac{3}{2}\log \left(T/T_{\rm breakdown} \right)$, previously derived for near-extremal black holes in Einstein gravity coupled to matter from the one-loop exact JT partition function, is universal across all models admitting an effective two-dimensional Horndeski description. We determine the general form of the scale at which this correction becomes dominant, $T_{\rm breakdown}$, in terms of the data of the $D$-dimensional theories. We illustrate our general results with charged black holes in Lovelock gravities and regular black holes in Quasitopological gravities.
