Experimental realization of an optical second with strontium lattice clocks [PDF]
Nature Communications, 2013 Progress in realizing the SI second had multiple technological impacts and enabled further constraint of theoretical models in fundamental physics. Caesium microwave fountains, realizing best the second according to its current definition with a relative uncertainty of 2-4 × 10(-16), have already been overtaken by atomic clocks referenced to an optical

Yb optical lattice clock at INRIM [PDF]
EFTF-2010 24th European Frequency and Time Forum, 2010 The Unit of Time in the International Systems of Units is realized at the relative frequency accuracy level of few parts in 10-16 by laser cooled Cesium fountains [1]; since 2003 INRIM has operated a laser cooled Cesium fountain with relative frequency accuracy at the level of 5×10-16 and has contributed with this frequency standard to the generation ...

Hyperpolarizability Effects in a Sr Optical Lattice Clock [PDF]
Physical Review Letters, 2006 We report the observation of the higher order frequency shift due to the trapping field in a $^{87}$Sr optical lattice clock. We show that at the magic wavelength of the lattice, where the first order term cancels, the higher order shift will not constitute a limitation to the fractional accuracy of the clock at a level of $10^{-18}$.

Demonstration of a time scale with the 87Sr optical lattice clock at NTSC
AIP Advances, 2023 Optical clocks have been applied to the generation of time scales since they provide superb uncertainty and instability in recent years. This paper presents the simulations about the impact of the optical clock’s operational strategies on the performance
