量子引力与对应原理

Quantum Gravity and the Correspondence Principle

Kaća Bradonjić

摘要:

量子引力的标准方法从前时空结构开始,并根据玻尔的对应原理,试图恢复低能极限下的伪黎曼流形。这些方法假设从量子引力到广义相对论的平滑过渡是成功的量子理论所共有的。然而,由于引力场和时空不能与物理场分开考虑,物理场性质的不连续性,例如在电弱对称破缺尺度下的质量损失,可能导致时空结构在普朗克尺度和广义相对论适用的尺度之间的变化。因此,正确的量子引力理论可能不会把广义相对论作为它的低能极限。

英文摘要:

Standard approaches to quantum gravity start with a pre-spacetime structure and attempt, in accordance with Bohr's correspondence principle, to recover the pseudo-Riemannian manifold in the low energy limit. These approaches assume there is a smooth transition from quantum gravity to general relativity common to successful quantum theories. However, as gravitational field, and hence spacetime, cannot be considered in isolation from physical fields, discontinuities in properties of physical fields, such as loss of mass at the electroweak symmetry breaking scale, may result in change of spacetime structure somewhere between the Planck scale and the scale where general relativity holds true. As a result, the correct theory of quantum gravity may not have general relativity as its low energy limit.
