Fundamental physics with the Square Kilometre Array (2018, result): “However, these results are in tension with terrestrial experiments using optical atomic clocks, which set a very stringent limit on the temporal variation of α (Rosenband et al., 2008).”
A strontium lattice clock with 3 × 10 − 17 ?> inaccuracy and its frequency (2013, background): “In addition to their role as future primary standards, optical clocks are of interest as sensitive probes in areas such as relativistic geodesy [9], tests of relativity [10, 11], and searches for variations of fundamental constants [1, 12, 13, 14, 15].”
Quantum simulations with cold trapped ions (2009, background): “Today, by using trapped ions as frequency standards unsurpassed ccuracy and precision has been reached (e.g., [Rosenband et al. 2008] and references ther in), and in addition, trapped ions are used for a wide range of investigations into fundamental questions of physics, for instance in the field…”

Microscopic Control and Detection of Ultracold Strontium in Optical-Tweezer Arrays (2018, background): “It further would be suitable for fundamental studies of squeezing and long-range entanglement on an optical clock transition [34, 48, 72, 73].”
How Accurate Is the Standard Second? (2011, background): “In the case of the second, for example, a new generation of “optical” atomic clocks is already claimed to have achieved “an accuracy that exceeds current realizations of the SI unit of time” (Rosenband et al. 2008, 1809).”
Entangled states of trapped atomic ions (2008, positive): “In addition to this demonstration, this protocol is now used in a high-accuracy optical clock based on single 27 Al p ion”
