First measurements of the index of refraction of gases for lithium atomic waves
Marion Jacquey, Matthias Büchner, Gérard Trénec +1
We report here the first measurements of the index of refraction of gases for lithium waves. Using an atom interferometer, we have measured the real and imaginary part of the index…
Phase noise due to vibrations in Mach-Zehnder atom interferometers
A. Miffre, M. Jacquey, M. Büchner +2
Atom interferometers are very sensitive to accelerations and rotations. This property, which has some very interesting applications, induces a deleterious phase noise due to the se…
Measurement of the electric polarizability of lithium by atom interferometry
Alain Miffre, Marion Jacquey, Matthias Buchner +2
We have built an atom interferometer and, by applying an electric field on one of the two interfering beams, we have measured the static electric polarizability of lithium with a 0…
High contrast Mach-Zehnder lithium atom interferometer in the Bragg regime
R. Delhuille, C. Champenois, M. Buchner +4
We have constructed an atom interferometer of the Mach-Zehnder type, operating with a supersonic beam of lithium. Atom diffraction uses Bragg diffraction on laser standing waves. W…
