摘要

我们证明了四维和真空中的史瓦西黑洞的静态潮汐洛夫数在奇偶-甚至是外部潮汐力的任意阶上都消失了。我们还确定了导致这一结果的潜在非线性对称性，当黑洞度规以轴对称静态Weyl坐标书写时，这种对称性变得明显。

Black holes in a gravitational field: the non-linear static love number of Schwarzschild black holes vanishes

We show that the static tidal Love number of Schwarzschild black holes in four dimensions and in the vacuum vanishes at any order in a parity-even external tidal force. We also identify the underlying non-linear symmetry which is responsible for this result and becomes manifest when the black hole metric is written in axsymmetric static Weyl coordinates.

期刊介绍： Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
