PMID: 26849591
Phys Rev Lett. 2016 Jan 22;116(3):033002. doi: 10.1103/PhysRevLett.116.033002. Epub 2016 Jan 21.

We demonstrate control of the absolute phase of an optical lattice with respect to a single trapped ion. The lattice is generated by off-resonant free-space laser beams, and we actively stabilize its phase by measuring its ac-Stark shift on...
