Schwarzschild黑洞某些性质的散射研究

A scattering approach to some aspects of the Schwarzschild Black Hole

Bernard Raffaelli

摘要:

本文研究了四维空间中自旋为j的无质量场与Schwarzschild黑洞相互作用中的s波散射。首先,利用傅立叶分析,我们表明,人们可以有一个简单而自然的描述物理附近的事件视界,而不使用任何共形场的方法。然后,在相同的“散射图片”,我们推导出解析的虚部的高阻尼准正常的复杂的频率,作为我们的分析的自然后果,我们表明,热效应,特别是霍金辐射,可以理解通过散射的传入s波的非零势垒的Regge-惠勒潜在的史瓦西黑洞。最后,借助于著名的高阻尼拟正规复频率的表达式,我们提出了一个启发式的扩展的“三重泡利统计量”建议的Motl,几年前。

英文摘要:

In this paper, we consider a massless field, with spin j, in interaction with a Schwarzschild black hole in four dimensions, focusing mainly our study on the s-wave scattering. First, using a Fourier analysis, we show that one can have a simple and natural description of the Physics near the event horizon without using any conformal field approaches. Then, within the same "scattering picture", we derive analytically the imaginary part of the highly damped quasinormal complex frequencies and, as a natural consequence of our analysis, we show that thermal effects and in particular Hawking radiation, can be understood through the scattering of an ingoing s-wave by the non null barrier of the Regge-Wheeler potential associated with the Schwarzschild black hole. Finally, with the help of the well-known expression of the highly damped quasinormal complex frequencies, we propose a heuristic extension of the "tripled Pauli statistics" suggested by Motl, some years ago.
