Abstract

Motivated by the similarity of the mathematical structure of Einstein's General Relativity in its weak field limit and of Maxwell's theory of electrodynamics it is shown that there are gravitational analogues of the Josephson effect and the quantum Hall effect. These effects can be combined to derive a gravitational analogue of the quantum/electric metrological triangle. The gravitational metrological triangle may have applications in metrology and could be used to investigate the relation of the Planck constant to fundamental particle masses. This allows for quantum tests of the Weak Equivalence Principle. Moreover, the similarity of the gravitational and the quantum/electrical metrological triangle can be used to test the universality of quantum mechanics.
