Coordinated international comparisons between optical clocks connected via fiber and satellite links

Thomas Lindvall, Marco Pizzocaro, Rachel M. Godun +62

Optical clocks provide ultra-precise frequency references that are vital for international metrology as well as for tests of fundamental physics. To investigate the level of agreem…

An Optical Lattice Clock with Spin-polarized 87Sr Atoms

Xavier Baillard, Mathilde Fouché, Rodolphe Le Targat +14

We present a new evaluation of an 87Sr optical lattice clock using spin polarized atoms. The frequency of the 1S0-3P0 clock transition is found to be 429 228 004 229 873.6 Hz with…
