论文摘要
我们研究了绕schwarzschild的源辐射的标量辐射，即圆形大地测量中的安提斯·西特黑洞。我们使用量子场理论在树级上使用量子场理论获得发射功率，而无穷大的反射边界条件。我们将结果与在Schwarzschild和Schwarzschild-De Sitter（$λ> 0 $）空位中获得的结果进行了比较。在Schwarzschild-De保姆时空中，我们观察到与Schwarzschild案例相比，与较低多极模式相关的发射功率的增强。相比之下，对于Schwarzschild-anti-de保姆时空，增强功能是较高的多极模式。
We study the scalar radiation emitted by a source orbiting a Schwarzschild--anti--de Sitter black hole in circular geodesics. We obtain the emitted power using quantum field theory in curved spacetimes at tree level with reflective boundary conditions at infinity. We compare our results with the ones obtained in Schwarzschild and Schwarzschild--de Sitter ($Λ> 0$) spacetimes. In the Schwarzschild-de Sitter spacetime we observe an enhancement of the emitted power associated to the lower multipole modes, when compared with the Schwarzschild case. In contrast, for the Schwarzschild-anti-de Sitter spacetime, the enhancement is rather of the higher multipole modes.
