We perform the experimental demonstration of the method proposed in [Phys. Rev. A 91, 063615 (2015)] to extract the differential phase in dual atom interferometers. From a single magneto-optical trap, we generate two atomic sources, vertically separated and free-falling synchronously, with the help of an accelerated lattice. We drive simultaneous Raman interferometers onto the two sources, and use the correlation with the vibration signal measured by a seismometer to extract the phase of each…

Separating the output ports of a Bragg interferometer via velocity selective transport

We report on the study of a detection scheme based on a Bloch separator in two-photon Bragg interferometers. We increase the spatial separation between the two output ports of the interferometer by

A dual-magneto-optical-trap atom gravity gradiometer for determining the Newtonian gravitational constant.

The design of the G measurement by atom interferometry is detailed, the experimental setup of the atom gravity gradiometer is reported, and a preliminary sensitivity of 3 × 10-9 g/Hz to differential gravity acceleration is obtained.

Simultaneous accurate determination of both gravity and its vertical gradient

We present a method for the accurate measurements of both the gravity acceleration and its vertical gradient using a dual atom interferometer, in principle free from any uncertainty related to the

Improving the accuracy of atom interferometers with ultracold sources

We report on the implementation of ultracold atoms as a source in a state of the art atom gravimeter. We perform gravity measurements with 10 nm s−2 statistical uncertainties in a so-far largely
