标题： Hawking Radiation -- Revisited

摘要： 本文在回顾霍金最初计算及其与瓦尔德工作成果的基础上重新审视了霍金辐射，发现可以得到一些额外的见解。 我们回顾了从解空间推导场论Hilbert空间的过程，随后基于第一性原理计算塌缩时空中的Bogoliubov系数。 我们证明这些计算可以推广到局域Killing视界以及渐近非平直空间的情形。 显示英文摘要

摘要： In this paper we revisited Hawking radiation in the light of the original calculations of Hawking and Wald and found that some additional insights can be gained. We review a "derivation" of the field theory Hilbert space from the space of solutions, followed by the calculation of Bogoliubov coefficients in a collapsed spacetime from first principles. We show that these calculations can be generalized to the case of local Killing horizons and also to asymptotically non-flat spaces.
