关于运动镜辐射和黑洞蒸发的伙伴粒子

On the partner particles for moving mirror radiation and black hole evaporation

M. Hotta, R. Schützhold, W. G. Unruh

摘要:

定义并计算了一个给定模式(如对应于黑洞发射的热粒子之一)的真空态的伙伴模式。明确计算的合作伙伴模式的数量的情况下,特别是对应于粒子探测器被激发的开启/关闭瞬态,或与热粒子发射的加速镜模型黑洞蒸发的模式。其中一个关键的结果是,伙伴模式在一般情况下只是一个真空涨落,和一个可以有伙伴模式位于一个区域中的状态不能区分从真空状态的任何一系列的本地测量,包括能量密度。也就是说,“信息”(与热发射的相关性)不需要与任何能量传输相关联。认为黑洞在其最后阶段发射出巨大能量是因为在黑洞幺正性假设下必须发射出的所有信息的想法被发现不一定是这样的。

英文摘要:

The partner mode with respect to a vacuum state for a given mode (like that corresponding to one of the thermal particles emitted by a black hole) is defined and calculated. The partner modes are explicitly calculated for a number of cases, in particular for the modes corresponding to a particle detector being excited by turn-on/turn-off transients, or with the thermal particles emitted by the accelerated mirror model for black hole evaporation. One of the key results is that the partner mode in general is just a vacuum fluctuation, and one can have the partner mode be located in a region where the state cannot be distinguished from the vacuum state by any series of local measurements, including the energy density. I.e., "information" (the correlations with the thermal emissions) need not be associated with any energy transport. The idea that black holes emit huge amounts of energy in their last stages because of all the information which must be emitted under the assumption of black-hole unitarity is found not necessarily to be the case.
