在AdS中创造恒星
Creating stars orbiting in AdS
摘要：
我们提出了一种方法来创建一个恒星轨道渐近AdS时空使用AdS/CFT对应。我们证明了在定义在2-球上的量子场论中，通过应用适当的源，定域星逐渐出现在对偶渐近AdS几何中。一旦创建了恒星，就可以从响应函数中观察到角位置。研究了产生的恒星参数与源参数之间的关系。我们表明，关于散装几何形状的信息可以从散装几何形状的恒星运动的观测中提取。
英文摘要：
We propose a method to create a star orbiting in an asymptotically AdS spacetime using the AdS/CFT correspondence. We demonstrate that by applying an appropriate source in the quantum field theory defined on a 2-sphere, the localized star gradually appears in the dual asymptotically AdS geometry. Once the star is created, the angular position can be observed from the response function. The relationship between the parameters of the created star and those of the source is studied. We show that information regarding the bulk geometry can be extracted from the observation of stellar motion in the bulk geometry.
