Atomic Clocks and Constraints on Variations of Fundamental Constants
Savely G. Karshenboim, Victor Flambaum, Ekkehard Peik
We consider an application of precision frequency measurements to searches for possible time variations of the fundamental physical constants. Current laboratory constraints on var…

2S hyperfine structure of atomic deuterium
N. Kolachevsky, P. Fendel, S. G. Karshenboim +1
We have measured the frequency splitting between the and hyperfine sublevels in atomic deuterium by an optical differential method based on two-photon D…

New limit on the present temporal variation of the fine structure constant
E. Peik, B. Lipphardt, H. Schnatz +3
The comparison of different atomic transition frequencies over time can be used to determine the present value of the temporal derivative of the fine structure constant alpha in a…
