  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…

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.
Imaging and addressing of individual fermionic atoms in an optical lattice
We demonstrate fluorescence microscopy of individual fermionic potassium atoms in a 527-nm-period optical lattice. Using electromagnetically induced transparency (EIT) cooling on the 770.1-nm D$_1$
Site-resolved imaging of fermionic ^{6}Li in an optical lattice.
We demonstrate site-resolved imaging of individual fermionic ^{6}Li atoms in a single layer of a 3D optical lattice. To preserve the density distribution during fluorescence imaging, we
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.

Angle-resolved photoemission spectroscopy (ARPES) measures the single-particle excitations of a many-body quantum system with energy and momentum resolution, providing detailed information about
A quantum gas microscope for detecting single atoms in a Hubbard-regime optical lattice
A quantum gas ‘microscope’ that bridges the two approaches to creating highly controllable quantum information systems, realizing a system in which atoms of a macroscopic ensemble are detected individually and a complete set of degrees of freedom for each of them is determined through preparation and measurement.
