单视界黑洞“Laser“与信息丢失问题的一个解

Single Horizon Black Hole "Laser" and a Solution of the Information Loss Paradox

摘要:

在这项工作中,我们表明,单视界黑洞的行为作为一个“激光”。它在许多方面与Corley和Jacobson关于双视界黑洞“激光”的工作在概念上类似。我们首先假设黑洞视界的周长是某些玻色子系统在大正则系综中约化康普顿波长的自然(整数)量子数。宏观黑洞的基态几乎完全被占据,而其它态几乎完全未被占据,这是一个典型的玻色凝聚。这个凝聚体中的系统数代表黑洞熵。对于微观黑洞,只有少数最低的能级被几乎相等的布居数(具有负化学势)占据,而所有其他的能态(具有正化学势)几乎都是空的。这意味着这里不仅发生自发辐射,而且发生与自发发射相当的受激发射。通过霍金蒸发,任何宏观的黑洞都会变成微观的黑洞,并在很大程度上产生辐射的相干受激发射。这意味着通过完全的黑洞蒸发,没有退相干,即信息损失。最后讨论了所提出的黑洞模型对应于弦T-对偶的质量对偶性。

英文摘要:

In this work we show that single horizon black hole behaves as a "laser". It is in many aspects conceptually analogous to Corley and Jacobson work on the two horizon black hole "laser". We started by proposition that circumference of the black hole horizon holds the natural (integer) quantum number of corresponding reduced Compton's wave length of some boson systems in great canonical ensemble. For macroscopic black hole ground state is practically totally occupied while other states are practically totally unoccupied which is a typical Bose condensation. Number of the systems in this condensate represents black hole entropy. For microscopic black hole few lowest energy levels are occupied with almost equivalent population (with negative chemical potential) while all other energy states (with positive chemical potential) are practically unoccupied. It implies that here not only spontaneous but also stimulated emission of radiation comparable with spontaneous emission occurs. By Hawking evaporation any macroscopic black hole turns out in a microscopic black hole that yields, in a significant degree, coherent stimulated emission of the radiation. It implies that by total black hole evaporation there is no decoherence, i.e. information loss. Finally, a mass duality characteristic for suggested black hole model corresponding to string T-duality is discussed.
