We demonstrate a single-site and single-atom-resolved fluorescence imaging of a bosonic Mott insulator of 7Li atoms in an optical lattice. The fluorescence images are obtained by implementing Raman sideband cooling on a deep two-dimensional square lattice, where we collect scattered photons with a high numerical aperture objective lens. The square lattice is created by a folded retro-reflected beam configuration that can reach 2.5 mK lattice depth from a single laser source. The lattice beam is…

Single-spin addressing in an atomic Mott insulator
TLDR
This work was able to flip the spin of individual atoms in a Mott insulator with sub-diffraction-limited resolution, well below the lattice spacing, and created arbitrary spin patterns by sequentially addressing selected lattice sites after freezing out the atom distribution.
Single-atom imaging of fermions in a quantum-gas microscope
Imaging individual atoms in an optical lattice with single-site resolution has so far only been possible for bosonic species, but thanks to electromagnetically-induced-transparency cooling fermionic…

TLDR
A quantum-gas microscope for fermionic atoms trapped in an optical lattice is realized, which allows one to probe strongly correlated fermions at the single-atom level and enables the direct observation of magnetic order, time-resolved measurements of the spread of particle correlations, and the detection of many-fermion entanglement.
