Making a denser optical lattice clock Some of today's most advanced clocks are made up of large numbers of atoms lined up in a one-dimensional (1D) optical lattice. The numbers improve clock stability, but atomic interactions can limit accuracy. Campbell et al. loaded their fermionic strontium atoms into a 3D optical lattice. The low temperatures and strong interactions ensured that the atoms avoided one another, resulting in a neat pattern where each lattice site was occupied by exactly one…

Suppression of Collisional Shifts in a Strongly Interacting Lattice Clock
TLDR
The effectiveness of this approach is demonstrated with a strontium lattice clock by reducing both the collisional frequency shift and its uncertainty to the level of 10−17, which eliminates the compromise between precision and accuracy in a many-particle system.

This work reports a different approach, in which atoms trapped in an optical lattice serve as quantum references, and the ‘optical lattice clock’ demonstrates a linewidth one order of magnitude narrower than that observed for neutral-atom optical clocks, and its stability is better than that of single-ion clocks.
