论文摘要
由旋转黑洞和CFT之间全息理论的先进进步的动机，我们探索了二射Kerr-Sen黑洞及其测量家庭的保形不变性。我们考虑在低频限制内黑洞的背景上进行中性无质量标量探针，并表明解决方案空间具有$ SL（2，r）\ times \ times sl（2，r）$等轴测。方位角的周期性识别对应于温度$ t_l，t_r $的自发共形对称性。使用参考文献上的中央费用计算。 [25]我们通过考虑所有相关场的贡献来重新计算，我们成功地从Cardy熵公式中得出了Bekenstein-Hawking熵。此外，我们还计算了从重力侧的吸收横截面，用于通用的非敌对对照二号kerr-kerr-sen黑洞和近超级测量的二型二氧体Kerr-sen黑洞。我们的计算表明，这些数量与CFT的计算完全匹配。因此，我们的发现进一步支持了旋转黑洞和CFT之间的双重性。
Motivated by advanced progress in the holographic theory between rotating black holes and CFT, we explore the conformal invariance on dyonic Kerr-Sen black hole and its gauged family. We consider a neutral massless scalar probe on the black holes' background within the low-frequency limit and exhibit that the solution space possesses $SL(2,R)\times SL(2,R)$ isometry. The periodic identification of the azimuthal angle corresponds to the spontaneous conformal symmetry breaking by temperatures $T_L,T_R$. Using the computation of the central charges on Ref. [25] that we recalculate by considering the contributions of all associated fields, we successfully derive the Bekenstein-Hawking entropy from Cardy entropy formula. Furthermore, we also calculate the absorption cross-section from gravity side for generic non-extremal dyonic Kerr-Sen black hole and near-extremal gauged dyonic Kerr-Sen black hole. Our calculations show that those quantities are in a perfect match with the calculation from CFT. Therefore, our findings further support the duality between rotating black holes and CFTs.
