论文摘要
本文通过分析GNSS信号传播的干扰介绍了基本物理的新测试。我们展示了GNSS信号如何在有效的标量场理论的通用框架中对精细结构常数$α$的空间变化敏感。这种有效的变化可能源于RF信号与暗物质团块和/或孤子结构的穿越。在宏观尺度上，随后的干扰等同于在不均匀培养基中传播期间发生的干扰。因此，我们提出了对真空通透性的“度量”作为基本物理学测试的“度量”。我们通过平面几何形状的简单模型中的简单模型中对预期签名的首次量化显示了方法的相关性。我们为此目的使用了域壁的测试模型，并专注于GNSS信号载体的可测量时间延迟。
This paper introduces new tests of fundamental physics by means of the analysis of disturbances on the GNSS signal propagation. We show how the GNSS signals are sensitive to a space variation of the fine structure constant $α$ in a generic framework of effective scalar field theories beyond the Standard Model. This effective variation may originate from the crossing of the RF signals with dark matter clumps and/or solitonic structures. At the macroscopic scale, the subsequent disturbances are equivalent to those which occur during the propagation in an inhomogeneous medium. We thus propose an interpretation of the "measure" of the vacuum permeability as a test of fundamental physics. We show the relevance of our approach by a first quantification of the expected signature in a simple model of a variation of $α$ according to a planar geometry. We use a test-bed model of domain walls for that purpose and focus on the measurable time delay in the GNSS signal carrier.
