High Performance Clocks and Gravity Field Determination

Autor: Müller, J., Dirkx, D., Kopeikin, S. M., Lion, G., Panet, I., Petit, G., Visser, P. N. A. M.

Time measured by an ideal clock crucially depends on the gravitational potential and velocity of the clock according to general relativity. Technological advances in manufacturing high-precision atomic clocks have rapidly improved their accuracy and

In the last 10 years, global seismic tomographic models have shown that some subducting slabs pond in the extended upper mantle transition zone (ETZ, between 660 and 1000 km depth), as do most “fat” plumes that originate at the core-mantle bounda

The MICROSCOPE mission was designed to test the weak equivalence principle (WEP), stating the equality between the inertial and the gravitational masses, with a precision of 10^{-15} in terms of the Eötvös ratio η. Its experimental test consisted
