黑洞反反应的量子玩具模型

Quantum toy model for black-hole back-reaction

Clovis Maia, Ralf Schützhold

摘要:

提出了一个简单的黑洞蒸发的量子场论玩具模型,并研究了霍金辐射在经典背景下的反作用。事实证明,在这种情况下,视界也被“推回”(即,内部区域收缩),但是这种反作用不是由能量守恒引起的,而是由动量平衡引起的。有效热容和诱导熵变可以有两个符号-取决于模型的参数。PACS:04.62.+ v,04.70.Dy.

英文摘要:

We propose a simple quantum field theoretical toy model for black hole evaporation and study the back-reaction of Hawking radiation onto the classical background. It turns out that the horizon is also ``pushed back'' in this situation (i.e., the interior region shrinks) but this back-reaction is not caused by energy conservation but by momentum balance. The effective heat capacity and the induced entropy variation can have both signs -- depending on the parameters of the model. PACS: 04.62.+v, 04.70.Dy.
