| 摘 要： | 首先利用Bogoliubov变换导出了Kruskal真空态与Schwarzschild真空态之间的联系,并把双模压缩幺正算符作用在Schwarzschild真空态上,得到了Kruskal真空态为Schwarzschild时空中的双模压缩真空态,并且可表示成纠缠态的形式,对应粒子的纠缠分别在视界的内部和外部区域.利用纠缠态进一步研究了Schwarzschild黑洞的Hawking辐射,得到了辐射率与Bekenstein-Hawking熵变有关,说明在黑洞辐射过程中携带量子信息是有可能的.

| Abstract: | The relation between Kruskal vacuum state and Schwarzschild vacuum state is firstly obtained by the Bogolyubov transformation. The Kruskal vacuum state is derived by acting by two-mode squeezing unitary operator on Schwar- zschild vacuum state, which is a two-mode squeezing vacuum state in the Schwarzschild space-time. Kruskal vacuum state is proved to an entangle state, corresponding to the entanglement of particles inside and outside of the horizon. By Kruskal vacuum state, such entangle state, we further... |
