  author={Kiryang Kwon and Kyungtae Kim and Junhyeok Hur and SeungJung Huh and Jae-yoon Choi},
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…

Site-Resolved Imaging of Ultracold Fermions in a Triangular-Lattice Quantum Gas Microscope
Quantum gas microscopes have expanded the capabilities of quantum simulation of Hubbard models by enabling the study of spatial spin and density correlations in square lattices. However, quantum gas
Single-atom-resolved fluorescence imaging of an atomic Mott insulator
Fluorescence imaging of strongly interacting bosonic Mott insulators in an optical lattice with single-atom and single-site resolution is reported, which fully reconstructs the atom distribution on the lattice and identifies individual excitations with high fidelity.

Single-spin addressing in an atomic Mott insulator
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

Quantum-gas microscope for fermionic atoms.
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.
