Improving the statistical analysis of anti-hydrogen free fall by using near edge events
Olivier Rousselle, Pierre Cladé, Saïda Guellati-Khélifa +2
An accurate evaluation of the gravity acceleration from the timing of free fall of anti-hydrogen atoms in the GBAR experiment requires to account for obstacles surrounding the anti…
Analysis of the timing of freely falling antihydrogen
Olivier Rousselle, Pierre Cladé, Saïda Guellati-Khélifa +2
We evaluate the accuracy to be expected for the measurement of free fall acceleration of antihydrogen in the GBAR experiment, accounting for the recoil transferred in the photodeta…
Velocity-dependent phase shift in a light-pulse atom interferometer
Léo Morel, Zhibin Yao, Pierre Cladé +1
Atom interferometry relies on the separation and recombination of atom wavepackets. When the two paths overlap perfectly at the end of the interferometer, the phase is insensitive…
State of the art in the determination of the fine structure constant and the ratio
Pierre Cladé, François Nez, François Biraben +1
The fine structure constant and the ratio between the Planck constant and the unified atomic mass are keystone constants for the determination of other funda…
Bloch oscillations in atom interferometry
Pierre Cladé
In Paris, we are using an atom interferometer to precisely measure the recoil velocity of an atom that absorbs a photon. In order to reach a high sensitivity, many recoils are tran…
State of the art in the determination of the fine structure constant: test of Quantum Electrodynamics and determination of h/mu
Rym Bouchendira, Pierre Cladé, Saïda Guellati-Khélifa +2
The fine structure constant has a particular status in physics. Its precise determination is required to test the quantum electrodynamics (QED) theory. The constant is also…
Compact atomic gravimeter based on a pulsed and accelerated optical lattice
Manuel Andia, Raphael Jannin, François Nez +3
We present a new scheme of compact atomic gravimeter based on atom interferometry. Atoms are maintained against gravity using a sequence of coherent accelerations performed by the…
Theoretical Analysis of a Large Momentum Beamsplitter using Bloch Oscillations
Pierre Cladé, Thomas Plisson, Saïda Guellati-Khélifa +2
In this paper, we present the implementation of Bloch oscillations in an atomic interferometer to increase the separation of the two interfering paths. A numerical model, in very g…
A promising method for the measurement of the local acceleration of gravity using Bloch oscillations of ultracold atoms in a vertical standing wave
Pierre Cladé, Saïda Guellati-Khélifa, Catherine Schwob +3
An obvious determination of the acceleration of gravity g can be deduced from the measurement of the velocity of falling atoms using a pi-pi pulses sequence of stimulated Raman tra…
