扭曲AdS_5黑洞与对偶CFTs

Warped AdS_5 Black Holes and Dual CFTs

Keiju Murata, Tatsuma Nishioka, Norihiro Tanahashi

摘要:

考虑了在负宇宙学常数的爱因斯坦引力场中,空间边界为压扁三球的黑洞解。我们数值求解了爱因斯坦方程组,得到了具有任意压缩参数的扭曲AdS黑洞解。当适当选取挤压参数时,该解成为普通的AdS-Schwarzschild解。基于这一事实,我们研究了压缩三球上N=4且耦合常数为零的超Yang-Mills理论,并证明了该理论的熵与扭曲AdS黑洞的熵近似一致,约为3/4.我们还研究了规范理论的禁闭/去禁闭跃迁。我们计算了扭曲AdS黑洞的Hawking-Page转变温度,发现引力转变温度与规范理论的转变温度定性一致.这些结果表明在压缩三球上的翘曲AdS解和N=4的超Yang-Mills理论之间存在对偶性。

英文摘要:

We consider a black hole solution whose spatial boundary is a squashed three sphere in Einstein gravity with negative cosmological constant. We solve the Einstein equations numerically and find a warped AdS black hole solution with arbitrary squashing parameter. This solution becomes the ordinary AdS-Schwarzschild solution when the squashing parameter is chosen appropriately. Motivated by this fact, we study N=4 super Yang-Mills theory with zero coupling constant on a squashed three sphere and show that the thermodynamical entropy of this theory roughly agrees with that of the warped AdS black hole up to a factor of 3/4. We also study the confinement/deconfinement transition of the gauge theory. We evaluate the approximate Hawking-Page transition temperature of the warped AdS black hole and find a qualitative agreement between the transition temperatures of the gravity and the gauge theory. These results suggest a duality between the warped AdS solution and N=4 super Yang-Mills theory on a squashed three sphere.
