Rydberg electrometry for optical lattice clocks [PDF]
Physical Review A, 2017 Electrometry is performed using Rydberg states to evaluate the quadratic Stark shift of the $5s^2$ $^1\textrm{S}_0-5s5p$ $^3\textrm{P}_0$ clock transition in strontium. By measuring the Stark shift of the highly excited $5s75d\;^1\textrm{D}_2$ state using electromagnetically induced transparency, we characterize the electric field with sufficient ...

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 $10^{-18}$.

A simplified optical lattice clock [PDF]
Applied Physics B, 2009 Existing optical lattice clocks demonstrate a high level of performance, but they remain complex experimental devices. In order to address a wider range of applications including those requiring transportable devices, it will be necessary to simplify the laser systems and reduce the amount of support hardware.

Frequency Standards and Metrology, 2009 At the previous Symposium on Frequency Standards and Metrology, H. Katori proposed using IS0 ---->3pO transitions in alkaline earth like atoms to make high performance optical clocks based on large numbers of neutral atoms tightly confined in an optical lattice.

Doubly Modulated Optical Lattice Clock: Interference and Topology [PDF]
Physical Review Letters, 2021 The quantum system under periodical modulation is the simplest path to understand the quantum non-equilibrium system, because it can be well described by the effective static Floquet Hamiltonian. Under the stroboscopic measurement, the initial phase is usually irrelevant.

A mercury optical lattice clock at LNE-SYRTE
Journal of Physics: Conference Series, 2016 We describe the development of an optical lattice clock based on mercury and the results obtained since the 7 th SFSM. We briefly present a new solution for the cooling laser system and an improved lattice trap that allows us to interrogate a few thousand atoms in parallel.
