Laboratory Limits on Temporal Variations of Fundamental Constants: An Update. arXiv preprint physics/0611088

Abstract

Precision comparisons of different atomic frequency standards over a period of a few years can be used for a sensitive search for temporal variations of fundamental constants. We present recent frequency measurements of the 688 THz transition in the 171 Yb + ion. For this transition frequency a record over six years is now available, showing that a possible… (More)
