A Search for Variations of Fundamental Constants using Atomic Fountain Clocks
H. Marion, F. Pereira Dos Santos, M. Abgrall +12
Over five years we have compared the hyperfine frequencies of 133Cs and 87Rb atoms in their electronic ground state using several laser cooled 133Cs and 87Rb atomic fountains with…
133Cs87Rb Laser Cooled Dual Fountain
D. Calonico, Y. Sortais, S. Bize +5
At BNM-SYRTE laboratories in Paris two 133Cs fountains and a 87Rb one have been already demonstrated. This paper illustrates the construction of a 87Rb and Cs dual fountain realize…
Controlling the cold collision shift in high precision atomic interferometry
F. Pereira Dos Santos, H. Marion, S. Bize +3
We present here a new method based on a transfer of population by adiabatic passage that allows to prepare cold atomic samples with a well defined ratio of atomic density and atom…
