论文摘要
在本文中,通过在Minkowski时空设置适当的边界,我们构建了三个玩具模型的空间,一个玩具黑洞,一个玩具白洞和一个玩具虫洞。基于这些模型的空间,我们讨论了鹰辐射和信息损失问题。通过计算地平线内外的场模式的数量,我们显示了玩具黑洞的热辐射。我们表明白洞具有热吸收。我们表明,在整个玩具虫洞的时空中,没有丢失的信息。此外,我们显示了黑洞辐射,白洞的吸收与奇异性下边界条件的选择无关。我们还显示了由两个特定边界条件引起的物理效应。
In this paper, by setting proper boundaries in the Minkowski spacetime, we construct three toy model spacetimes, a toy black hole, a toy white hole, and a toy wormhole. Based on these model spacetimes, we discuss the Hawking radiation and the information loss problem. By counting the number of the field modes inside and outside the horizon, we show the thermal radiation of the toy black hole. We show that the white hole have a thermal absorption. We show that in the whole toy wormhole spacetime, there is no information lost. In addition, we show the black hole radiation and the white hole absorption are independent of the choices of boundary conditions at the singularity. We also show the physical effects caused by two particular boundary conditions.
