接近黑洞极限的静态引力场中标量粒子的能级

Energy levels of a scalar particle in a static gravitational field close to the black hole limit

G. H. Gossel, J. C. Berengut, V. V. Flambaum

摘要:

在具有Florides度规和Schwarzschild度规描述的有限尺寸物体的引力场中,我们得到了标量粒子的束缚态能级,对于这些度规,只有当度规中出现奇点时,才存在能量为零的束缚态(束缚能等于标量粒子的质量).对于弗洛里德斯度规,这种奇异性发生在黑洞极限,而对于常密度(史瓦西内部)度规,它对应于中心的无穷大压力。此外,能量谱被证明成为准连续的度量变得奇异。

英文摘要:

The bound-state energy levels of a scalar particle in the gravitational field of finite-sized objects with interiors described by the Florides and Schwarzschild metrics are found. For these metrics, bound states with zero energy (where the binding energy is equal to the mass of the scalar particle) only exist when a singularity occurs in the metric. For the Florides metric this singularity occurs in the black hole limit, while for the constant density (Schwarzschild interior) metric it corresponds to infinite pressure at the center. Moreover, the energy spectrum is shown to become quasi-continuous as the metric becomes singular.
