Vaidya时空中粒子探测器的响应

On the Response of Particle Detectors in Vaidya Spacetimes

Alex Venditti, Charles Dyer

摘要:

利用相互作用图像的形式,我们计算了一个表达式的Wightman函数的球对称模式的量子Klein-Gordon标量场在一般Vaidya时空与进入零尘。它表明,粒子探测器以下的类时轨迹是在基态在某些时间外的崩溃壳将响应独立于输入的零尘的配置,如果响应是在任何时间外的崩溃壳。对于探测器采取的是在基态在一个时间内的壳,它示出,它们的响应将取决于配置的进入零灰尘。相关的信息丢失的悖论进行了讨论。

英文摘要:

Using the formalism of the interaction picture we calculate an expression for the Wightman function for only the spherically symmetric modes of a quantum Klein-Gordon scalar field in a general Vaidya spacetime with ingoing null dust. It is demonstrated that particle detectors following time-like trajectories that are in the ground state at some time outside of the collapsing shell will respond independently from the configuration of the ingoing null dust if the response is taken at any time outside of the collapsing shell. For detectors that are taken to be in the ground state at a time interior to the shell it is shown that their response will depend on the configuration of the ingoing null dust. Relevance to the information loss paradox is discussed.
