扩展引力钟罗盘:新的精确解和模拟

Extended gravitational clock compass: new exact solutions and simulations

Gerald Neumann, Dirk Puetzfeld, Guillermo F. Rubilar

摘要:

通过扩展引力钟罗盘的框架,我们展示了如何在广义相对论的背景下,使用一组适当准备的时钟来提取关于引力场的信息。扩展和标准时钟罗盘之间的概念差异突出显示。特别注意的是运动学量的影响,测量过程中和指南针的设置。此外,我们提出的加速度和曲率分量的推理过程的模拟结果。几个例子的曲率分量的后验概率分布的计算不同的策略进行了讨论。这使我们能够预测在实际测量中可以确定的物理量的精度。

英文摘要:

By extending the framework of the gravitational clock compass we show how a suitably prepared set of clocks can be used to extract information about the gravitational field in the context of General Relativity. Conceptual differences between the extended and the standard clock compass are highlighted. Particular attention is paid to the influence of kinematic quantities on the measurement process and the setup of the compass. Additionally, we present results of simulations of the inference process for the acceleration and the curvature components. Several examples of different strategies for the computation of the posterior probability distributions of the curvature components are discussed. This allows us to anticipate the precision with which physical quantities could be determined in a realistic measurement.
