Optical lattices

In this paper we will review experimental and theoretical developments in the study of optical lattices. In Section II we introduce our subject by discussing the key one-dimensional model system for laser cooling and trapping in optical lattices. In Section III we discuss crystallography of various lattice geometries, and in Section IV we cover the basic laser cooling theory in optical lattices. Section V reviews experimental work that probes optical lattices through spectroscopy, and finally, in Section VI we discuss new developments in the field and possible future directions. 71 refs., 11 figs
