| Popis: | Lithium is an important element in atomic quantum gas experiments because its interactions are highly tunable, due to broad Feshbach resonances and zero-crossings, and because it has two stable isotopes, $^6$Li, a fermion, and $^7$Li, a boson. Although lithium has special value for these reasons, it also presents experimental challenges. In this article, we review some of the methods that have been developed or adapted to confront these challenges, including beam and vapor sources, Zeeman slowers, sub-Doppler laser cooling, laser sources at 671 nm, and all-optical methods for trapping and cooling. Additionally, we provide spectral diagrams of both $^6$Li and $^7$Li, and present plots of Feshbach resonances for both isotopes. Comment: 30 pages, 8 figures |
