Fundamental constants are a cornerstone of our physical laws. Any constant varying in
space and/or time would reflect the existence of an almost massless field that couples to …

According to the weak equivalence principle, all bodies should fall at the same rate in a
gravitational field. The MICROSCOPE satellite, launched in April 2016, aims to test its …

Inertial sensors relying on atom interferometry offer a breakthrough advance in a variety of
applications, such as inertial navigation, gravimetry or ground-and space-based tests of …

The gravitational couplings of matter are studied in the presence of Lorentz and CPT
violation. At leading order in the coefficients for Lorentz violation, the relativistic quantum …

We explore a version of the cosmological dilaton-fixing and decoupling mechanism in which
the dilaton dependence of the low-energy effective action is extremized for infinitely large …

In a recently proposed scenario, where the dilaton decouples while cosmologically attracted
towards infinite bare string coupling, its residual interactions can be related to the amplitude …

The weak equivalence principle (WEP), stating that two bodies of different compositions
and/or mass fall at the same rate in a gravitational field (universality of free fall), is at the very …

LISA Pathfinder, formerly known as SMART-2, is the second of the European Space
Agency's Small Missions for Advance Research and Technology, and is designed to pave …

Abstract The proposed mission “Space Atomic Gravity Explorer”(SAGE) has the scientific
objective to investigate gravitational waves, dark matter, and other fundamental aspects of …

The space mission MICROSCOPE dedicated to the test of the equivalence principle (EP)
operated from April 25, 2016 until the deactivation of the satellite on October 16, 2018. In this …
