Development of a strontium optical lattice clock for the SOC mission on the ISS [PDF]

, 2016
The ESA mission "Space Optical Clock" project aims at operating an optical lattice clock on the ISS in approximately 2023. The scientific goals of the mission are to perform tests of fundamental physics, to enable space-assisted relativistic geodesy and ...

Systematic study of the $^{87}$Sr clock transition in an optical lattice [PDF]

, 2005
With ultracold $^{87}$Sr confined in a magic wavelength optical lattice, we present the most precise study (2.8 Hz statistical uncertainty) to-date of the $^1S_0$ - $^3P_0$ optical clock transition with a detailed analysis of systematic shifts (20 Hz ...

Lattice-induced non-adiabatic frequency shifts in optical lattice clocks [PDF]

, 2010
We consider the frequency shift in optical lattice clocks which arises from the coupling of the electronic motion to the atomic motion within the lattice.

Accuracy Evaluation of an Optical Lattice Clock with Bosonic Atoms [PDF]

, 2007
We report the first accuracy evaluation of an optical lattice clock based on the 1S0 - 3P0 transition of an alkaline earth boson, namely 88Sr atoms. This transition has been enabled using a static coupling magnetic field.

Hyperpolarizability and operational magic wavelength in an optical lattice clock [PDF]

, 2017
Optical clocks benefit from tight atomic confinement enabling extended interrogation times as well as Doppler- and recoil-free operation. However, these benefits come at the cost of frequency shifts that, if not properly controlled, may degrade clock ...

Strontium optical lattice clocks for practical realization of the metre and secondary representation of the second [PDF]

, 2015
We present a system of two independent strontium optical lattice standards probed with a single shared ultra-narrow laser. The absolute frequency of the clocks can be verified by the use of Er:fiber optical frequency comb with the GPS-disciplined Rb ...

A transportable strontium optical lattice clock [PDF]

, 2014
We report on a transportable optical clock, based on laser-cooled strontium atoms trapped in an optical lattice. The experimental apparatus is composed of a compact source of ultra-cold strontium atoms including a compact cooling laser set-up and a ...
