圈量子引力中的黑洞

Black Holes in Loop Quantum Gravity

Alejandro Perez

摘要:

本文综述了在圈量子引力框架下黑洞物理的研究结果。这些结果的关键特征是通过这种量子引力方法预测的普朗克尺度几何量的离散性。当应用于广义相对论的作用量时,量子离散性直接来自正则量子化的规定,广义相对论适用于引力与规范场,特别是与费米子的耦合。普朗克离散性和因果关系的考虑为理解接近平衡态的黑洞的热性质提供了基本结构。离散性也提供了一个新的视角来看待(目前)更多的投机性问题,比如那些关于黑洞蒸发中信息命运的问题。离散性的假设也导致了有趣的现象学,并可能产生观测结果。圈量子引力理论是一个发展中的纲领。这篇评论报告了它的成就和开放的问题,在教学的方式,重点是量子方面的黑洞物理。

英文摘要:

This is a review of the results on black hole physics in the framework of loop quantum gravity. The key feature underlying the results is the discreteness of geometric quantities at the Planck scale predicted by this approach to quantum gravity. Quantum discreteness follows directly from the canonical quantization prescription when applied to the action of general relativity that is suitable for the coupling of gravity with gauge fields and specially with fermions. Planckian discreteness and causal considerations provide the basic structure for the understanding of the thermal properties of black holes close to equilibrium. Discreteness also provides a fresh new look at more (at the moment) speculative issues such as those concerning the fate of information in black hole evaporation. The hypothesis of discreteness leads also to interesting phenomenology with possible observational consequences. The theory of loop quantum gravity is a developing program. This review reports its achievements and open questions in a pedagogical manner with an emphasis on quantum aspects of black hole physics.
