Platform and environment requirements of a satellite quantum test of the weak equivalence principle at the 10^-17 level

Métris, Gilles; Struckmann, Christian; Corgier, Robin +6 more

The space-time explorer and quantum equivalence principle space test (STE-QUEST) recently proposed, aims at performing a precision test of the weak equivalence principle (WEP), a fundamental cornerstone of general relativity. Taking advantage of the ideal operation conditions for high-precision quantum sensing on board of a satellite, it aims to d…

Violation of the equivalence principle induced by oscillating rest mass and transition frequency, and its detection in atom interferometers

Wolf, Peter; Gué, Jordan; Hees, Aurélien

We present a theoretical investigation of the expected experimental signals produced by freely falling atoms with time oscillating mass and transition frequency. These oscillations could be produced in a variety of models, in particular, models of scalar dark matter nonuniversally coupled to the standard matter such as axionlike particles and dila…

Weak equivalence principle and nonrelativistic limit of general dispersion relations

Hohmann, Manuel; Pfeifer, Christian; Wagner, Fabian

We study the weak equivalence principle in the context of modified dispersion relations, a prevalent approach to quantum gravity phenomenology. We find that generic modified dispersion relations violate the weak equivalence principle. The acceleration in general depends on the mass of the test body, unless the Hamiltonian is either 2-homogeneous i…
