二维Schwarzschild黑洞的熵结构与信息丢失(英文)

Entropy structure of 2d-Schwarzschild black holes and information loss

利用相干态的理论讨论了二维Schwarzschild黑洞的熵结构 ,并由此对信息丢失问题进行了考察。分析表明“丢失”的信息并没有丢失 ,而是可能被“冻结”

By means of the coherent state representation, the entropy structure of a 1+1 dimensional Schwarzschild black hole is discussed , and starting with the entropy structure, the problem concerned with the information loss is also investigated. It may be shown that the 'lost information' does not lose but 'be frozen' on the event horizon of the hole.
