四维静态黎曼时空中的Hawking辐射

本文论证了四维静态黎曼时空中的视界普遍会产生Hawking辐射,辐射温度正比于视界的表面重力k。并把这一工作推广到电磁场存在的情况,指出影响Hawking辐射谱的静电势既可起源于视界内部的电荷,也可起源于视界外部的电荷。上述工作统一了史瓦西黑洞、Reissner-Nordstrm黑洞、Schwarzschild-deSitter宇宙的Hawking辐射和匀加速系的Rindler辐射。指出在Rindler辐射的问题上等效原理依然成立,Rindler辐射确实来源于该参考系的视界,Hawking辐射与时空的曲率 关键词：

HAWKING RADIATION IN FOUR DIMENSIONAL STATIC RIEMANN SPACETIME

It has been proved in this paper that in general the horizons in 4-dimensional static Riemann spacetime will produce Hawking radiations and the radiative temperature is proportional to the surface gravity k of the horizon.This work is extended to the state that there exist electromagnetic fields. We point out that the static electric potential which effects Hawking radiative spectrum may originate from the electrie charge inside the hos,izoii as well as outside the hosizon.The Rindler radiations in uniform accelerated frames and the Hawking radiations from Schwarzsehild B. H., Keissner-Nordstrom B. H. as wall as Schwarzschild-de Sitter universe horizons are the special cases of our present general theory.It is pointed out that the equivalence principle Is still effective and Rindlerradiations do originate from the horizons of the Rindler frames of reference. Hawkingradiation only has relation with dynamic effect K near the horizon, but has no relation with curvature of the spaeetime.
