球对称坍缩与黑洞蒸发

Spherical collapse and black hole evaporation

Madhavan Varadarajan

AI总结:

本文研究球对称引力与标量场耦合模型,利用半经典 Einstein 方程描述蒸发黑洞,并通过未来零无穷远处的正通量平衡律提出信息可经由量子延拓重新显现。

摘要:

我们考虑球对称引力与一个球对称标量场相耦合,该耦合具有依赖于 Areal Radius(面积半径)的特定形式。经典坍缩由 Vaidya 解描述。半经典 Einstein 方程具有良好定义。其解描述了一个正在蒸发的黑洞。未来零无穷远处的一条平衡定律将经反作用修正的 Bondi 质量的变化率与一个明显为正的通量联系起来。其具体形式暗示了未来零无穷远的一种量子延拓,沿着这一延拓,包括坍缩物质中信息在内的所有信息预计都会显现出来。

英文摘要:

We consider spherically symmetric gravity coupled to a spherically symmetric scalar field with a specific coupling which depends on the Areal Radius. Classical collapse is described by the Vaidya solution. The semiclassical Einstein equations are well defined. Their solution describes an evaporating black hole. A balance law at future null infinity relates the rate of change of a back reaction-corrected Bondi mass to a manifestly positive flux. Its detailed form suggests a quantum extension of future null infinity along which all information including that in the collapsing matter is expected to emerge.
