度规涨落与弱等价原理

Metric fluctuations and the Weak Equivalence Principle

Ertan Göklü, Claus Lämmerzahl

摘要:

我们描述的空间-时间波动的度量在一个给定的背景度量的小波动。从最小耦合Klein-Gordon方程出发,在弱场近似下,通过对非相对论极限下量子粒子给出的有限时空尺度的平均,得到了修正的薛定谔方程。占主导地位的修改包括在一个异常的惯性质量张量,这取决于粒子的类型和波动的情况。在本文中考虑的情况是一个最简单的时空波动的图片,并给出了一个明显违反弱等价原理,并在一般情况下,违反洛伦兹不变性的存在性证明。

英文摘要:

We describe space--time fluctuations by means of small fluctuations of the metric on a given background metric. From a minimally coupled Klein--Gordon equation we obtain within a weak-field approximation up to second order and an averaging procedure over a finite space--time scale given by the quantum particle in the non--relativistic limit a modified Schrödinger equation. The dominant modification consists in an anomalous inertial mass tensor which depends on the type of particle and on the fluctuation scenario. The scenario considered in this paper is a most simple picture of spacetime fluctuations and gives an existence proof for an apparent violation of the weak equivalence principle and, in general, for a violation of Lorentz invariance.
