Enhancing optical clocks: strontium lattice clock with a record precision and accuracy
We present the latest evaluation of the systematic uncertainty of the JILA 1D Sr optical lattice clock, which has achieved a record-low systematic uncertainty of 8.1 × 10<sup>−19</sup> in fractional frequency units. We discuss the strategies for reducing the uncertainties and their results.
