黑洞信息之谜:一种通用的字符串启发方法

Black-hole information puzzle: A generic string-inspired approach

H. Nikolic

摘要:

从弦论出发,将黑洞(BH)信息之谜的起源追溯到负频率Hawking粒子上的密度矩阵的物理意义这一假设.相反,把它们当作虚粒子,按照BH热力学定律的方式必然被BH吸收,并且只在物理BH态上追踪密度矩阵,完全蒸发就与幺正性相容了。

英文摘要:

Given the insight steming from string theory, the origin of the black-hole (BH) information puzzle is traced back to the assumption that it is physically meaningful to trace out the density matrix over negative-frequency Hawking particles. Instead, treating them as virtual particles necessarily absorbed by the BH in a manner consistent with the laws of BH thermodynamics, and tracing out the density matrix only over physical BH states, the complete evaporation becomes compatible with unitarity.
