该研究针对近期关于大黑洞存在量子信息导致的记忆负担效应的论断，分析全息时空模型的黑洞蒸发，发现该模型中不存在此类效应，其源于费米黄金规则与细致平衡原理，且取决于模型的能量定义与因果实现方式。

近期论文[1]声称，一般量子信息考量对大黑洞的性质施加了宏观约束，这可能以宇宙学和天体物理学上有意义的方式影响黑洞的寿命。我们研究了全息时空（HST）模型[2]中的黑洞蒸发，该模型似乎存在导致其与半经典预期产生偏差的“记忆负担”效应，并解释了为何在这些模型中不存在此类效应。这本质上是费米黄金规则/细致平衡原理的结果，但关键取决于HST模型中能量的定义以及因果关系的实现方式。
英文摘要
Recent papers\cite{dvali} have claimed that general quantum information considerations put macroscopic constraints on the properties of large black holes, which can affect their lifetimes in cosmologically and astrophysically interesting ways. We examine black hole evaporation in Holographic Space Time (HST) models\cite{hstbh}, which appear to have the {\it memory burden} effect responsible for these deviations from semi-classical expectations, and explain why, in those models, no such effect exists. It is basically a consequence of Fermi's Golden Rule/The Principle of Detailed Balance, but depends crucially on both the definition of energy in HST models and the way in which causality is implemented.
