New Limits to the Drift of Fundamental Constants from Laboratory Measurements
M. Fischer, N. Kolachevsky, M. Zimmermann +17
We have remeasured the absolute - transition frequency in atomic hydrogen. A comparison with the result of the previous measurement performed in 1999 sets a l…

Cold Atom Clocks, Precision Oscillators and Fundamental Tests
S. Bize, P. Wolf, M. Abgrall +17
We describe two experimental tests of the Equivalence Principle that are based on frequency measurements between precision oscillators and/or highly accurate atomic frequency stand…
