New Limits to the Drift of Fundamental Constants from Laboratory Measurements

M. Fischer, N. Kolachevsky, M. Zimmermann +17

We have remeasured the absolute $1 S$ - $2 S$ transition frequency $ν_{H}$ in atomic hydrogen. A comparison with the result of the previous measurement performed in 1999 sets a l…

Precision Spectroscopy of Atomic Hydrogen and Variations of Fundamental Constants

M. Fischer, N. Kolachevsky, M. Zimmermann +14

In 2003 we have measured the absolute frequency of the $(1 S, F = 1, m_{F} = \pm 1) \leftrightarrow (2 S, F^{'} = 1, m_{F}^{'} = \pm 1)$ two-photon transition in atomic hydrogen. We observed a variati…

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…
