Kerr-Bolt时空的隐共形对称性

Hidden Conformal Symmetry of Kerr-Bolt Spacetimes

A. M. Ghezelbash, V. Kamali, M. R. Setare

摘要:

我们将最近提出的隐共形对称性推广到具有转动参数和NUT扭曲的四维时空。研究了Kerr Bolt时空背景下无质量标量场的波动方程,证明了在“近区”,波动方程可以用$SL(2,R)_L \times SL(2,R)_R$ Casimir二次算子再现.此外,我们还利用Cardy公式计算了对偶CFT的微观熵,并找到了与Kerr-Bolt时空的Bekenstein-Hawking熵的完美匹配。近区标量场的吸收截面也与双CFT的微观吸收截面相匹配。

英文摘要:

We extend the recent proposal of hidden conformal symmetry to the four-dimensional spacetimes with rotational parameter and NUT twist. We consider the wave equation of a massless scalar field in background of Kerr-Bolt spacetimes and show in the "near region", the wave equation can be reproduced by the $SL(2,R)_L \times SL(2,R)_R$ Casimir quadratic operators. Moreover, we compute the microscopic entropy of the dual CFT by Cardy formula and find a perfect match to Bekenstein-Hawking entropy of Kerr-Bolt spacetimes. The absorption cross section of a near region scalar field also matches to microscopic absorption cross section of the dual CFT.
