史瓦西黑洞上的静态探测器和圆测地线探测器

Static detectors and circular-geodesic detectors on the Schwarzschild black hole

Lee Hodgkinson, Jorma Louko, Adrian C. Ottewill

摘要:

本文主要用数值方法研究了(3+1)维Schwarzschild时空中Boulware态、Hartle-Hawking态和Unruh态下Unruh-DeWitt粒子探测器与无质量标量场耦合对静态探测器和圆测地线上探测器的响应。对于静态探测器,在探测器能隙较大的情况下,Hartle-Hawking态的响应在局域Hawking温度下表现出已知的热性,而Unruh态的响应在局域Hawking温度下表现出热性.对于圆形测地线检测器,我们发现的证据的热量在一个大的能隙的极限为Hartle-Hawking和Unruh状态,在一个温度超过多普勒频移的本地Hawing温度。三种状态之间的详细定量比较。在Hartle-Hawking状态的响应进行了比较,在闵可夫斯基真空和闵可夫斯基热状态的相应的Rindler,漂移Rindler,和循环加速轨迹的响应。分析在一阶扰动理论内进行,并且在本质上依赖于平稳性。

英文摘要:

We examine the response of an Unruh-DeWitt particle detector coupled to a massless scalar field on the (3+1)-dimensional Schwarzschild spacetime, in the Boulware, Hartle-Hawking and Unruh states, for static detectors and detectors on circular geodesics, by primarily numerical methods. For the static detector, the response in the Hartle-Hawking state exhibits the known thermality at the local Hawking temperature, and the response in the Unruh state is thermal at the local Hawking temperature in the limit of a large detector energy gap. For the circular-geodesic detector, we find evidence of thermality in the limit of a large energy gap for the Hartle-Hawking and Unruh states, at a temperature that exceeds the Doppler-shifted local Hawing temperature. Detailed quantitative comparisons between the three states are given. The response in the Hartle-Hawking state is compared with the response in the Minkowski vacuum and in the Minkowski thermal state for the corresponding Rindler, drifted Rindler, and circularly accelerated trajectories. The analysis takes place within first-order perturbation theory and relies in an essential way on stationarity.
