In this paper we examine the possibility of a Josephson AC effect between two superconductors induced by the Earth's gravitational field, making use of the gravito-Maxwell formalism. The theoretical framework exploits the symmetry between the weak field expansion of the gravitational field and the standard Maxwell formulation, combined with the Josephson junction physics. We also suggest a suitable experimental setup, analysing also the related possible difficulties in measurements.

弱引力场引起的约瑟夫森交流效应

在本文中，我们利用引力-麦克斯韦公式研究了由地球引力场引起的两个超导体之间的约瑟夫森交流效应的可能性。理论框架利用引力场的弱场扩展与标准麦克斯韦公式之间的对称性，并结合约瑟夫森结物理学。我们还建议了一个合适的实验设置，分析了测量中可能存在的相关困难。
