AI总结:

该研究利用克尔/共形场论对应,探讨旋转弗罗伊登塔尔对偶对极端克尔-纽曼黑洞对偶热二维共形场论的影响,发现其映射不同温度和中心荷但渐近态密度相同的CFT,还讨论了双极端旋转黑洞的相关特性。

摘要:

旋转弗罗伊登塔尔对偶(RFD)将两个极端克尔-纽曼(KN)黑洞(BHs)联系起来,它们具有不同的角动量和电磁电荷,但贝肯斯坦-霍金熵相同。通过克尔/共形场论对应(及其KN扩展),四维渐近平坦极端KN黑洞被赋予一个对偶的热二维共形场论(CFT),使得CFT的卡迪熵与KN黑洞自身的贝肯斯坦-霍金熵相同。利用这一联系,我们研究了RFD对KN极端(或双极端)黑洞对偶热CFT的影响。我们发现,RFD映射两个不同的热二维CFT,它们具有不同的温度和中心荷,但具有相同的渐近态密度,从而匹配卡迪熵。我们还讨论了RFD对双极端旋转黑洞的作用,发现非旋转极限下存在虚假分支,并确定对于这类黑洞解,RFD的像必然过度旋转。

英文摘要:

Rotational Freudenthal duality (RFD) relates two extremal Kerr-Newman (KN) black holes (BHs) with different angular momenta and electric-magnetic charges, but with the same Bekenstein-Hawking entropy. Through the Kerr/CFT correspondence (and its KN extension), a four-dimensional, asymptotically flat extremal KN BH is endowed with a dual thermal, two-dimensional conformal field theory (CFT) such that the Cardy entropy of the CFT is the same as the Bekenstein-Hawking entropy of the KN BH itself. Using this connection, we study the effect of the RFD on the thermal CFT dual to the KN extremal (or doubly-extremal) BH. We find that the RFD maps two different thermal, two-dimensional CFTs with different temperatures and central charges, but with the same asymptotic density of states, thereby matching the Cardy entropy. We also discuss the action of the RFD on doubly-extremal rotating BHs, finding a spurious branch in the non-rotating limit, and determining that for this class of BH solutions the image of the RFD necessarily over-rotates.
