The article "Optics and interferometry with atoms and molecules" by Alexander D. Cronin, Jörg Schmiedmayer, and David E. Pritchard reviews the field of atom optics and interferometry, focusing on the manipulation of atomic and molecular matter waves. The authors highlight the historical development of techniques from atomic beams to coherent atom optics, emphasizing the importance of phase coherence in achieving interference effects. They discuss various tools for coherent atom optics, including diffraction by nanostructures and laser light, three-grating interferometers, and double wells on atom chips. The review also covers the scientific advances resulting from the application of atom interferometers, categorized into fundamental quantum science, precision metrology, and atomic and molecular physics. The article emphasizes the advantages of atom interferometry over other types of interferometers, such as higher precision, better portability, and lower cost, and discusses specific experiments that have utilized these techniques, including measurements of rotations, gravity, atomic polarizability, and atom-surface interactions.The article "Optics and interferometry with atoms and molecules" by Alexander D.
