If you have a question about this talk, please contact Vincent Boyer. For thousands of years, man used the rotation of the Earth as a reference for timekeeping. But the modern world requires far greater precision and the advent of atomic clocks has enabled fractional uncertainties in the realisation of the SI second to improve by many orders of magnitude. With ever improved accuracy in measurements of time and frequency, it also becomes possible to test fundamental physics at previously inscrutable levels. This talk gives an overview of the performance of atomic clocks, and presents NPL ’s work on the ytterbium ion optical clock as a specific example. This talk is part of the Cold Atoms series. ## This talk is included in these lists:Note that ex-directory lists are not shown. |
