常曲率空间中的突现引力

Emergent Gravity in Spaces of Constant Curvature

Orlando Alvarez, Matthew Haddad

摘要:

在物理理论中,能量(作用量)局部化在常曲率空间的子流形附近,能量(或作用量)有一个普适表达式。我们推导出一个多极展开的能量,有一个有限数量的条款,并依赖于内在的几何不变量的子流形和外在的不变量的嵌入的子流形。这是一对文章中的第二篇,在这两篇文章中,我们试图发展一个理论的涌现引力所产生的嵌入一个子流形到周围的空间配备了量子场论。我们的理论方法需要推广的公式由于赫尔曼外尔。虽然第一篇论文讨论了在欧几里得(闵可夫斯基)空间的框架,在这里,我们讨论这个框架如何推广到空间的常数截面曲率。我们主要关注反德西特空间。然后,我们讨论了这样的理论如何能产生一个宇宙学常数和普朗克质量,是在合理的范围内的实验值。

英文摘要:

In physical theories where the energy (action) is localized near a submanifold of a constant curvature space, there is a universal expression for the energy (or the action). We derive a multipole expansion for the energy that has a finite number of terms, and depends on intrinsic geometric invariants of the submanifold and extrinsic invariants of the embedding of the submanifold. This is the second of a pair of articles in which we try to develop a theory of emergent gravity arising from the embedding of a submanifold into an ambient space equipped with a quantum field theory. Our theoretical method requires a generalization of a formula due to by Hermann Weyl. While the first paper discussed the framework in Euclidean (Minkowski) space, here we discuss how this framework generalizes to spaces of constant sectional curvature. We focus primarily on anti de Sitter space. We then discuss how such a theory can give rise to a cosmological constant and Planck mass that are within reasonable bounds of the experimental values.
