Abstract:
Optical atomic clocks based on the spectroscopy of strontium (Sr) atoms currently provide the most accurate time and frequency measurements. They reach fractional frequency uncertainties in the range of 10−18 [1], which makes them promising candidates for the redefinition of the second and for improving, for example, the accuracy of satellite navigation.
