Atomic physics yield a better overall description, i.e. the atomic orbital model, but it also provided a new theoretical basis for chemistry (quantum chemistry) and spectroscopy. Since the Second World War, both theoretical and experimental fields have advanced at a rapid pace. This can be attributed to progress in computing technology, which has allowed larger and more sophisticated models of atomic structure and associated collision processes. Similar technological advances in accelerators, detectors, magnetic field generation and lasers have greatly assisted experimental work. Atomic physics Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an
Institute for Theoretical Atomic, Molecular and Optical Physics who was later joined as joint director by Misha Lukin. In 2016 the director is Hossein Sadeghpour. Institute for Theoretical Atomic, Molecular and Optical Physics The Institute for Theoretical Atomic, Molecular and Optical Physics (ITAMP) is an international scientific learned society based at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. It was established in 1988 to alleviate a perceived shortage of theorists in atomic, molecular, and optical physics (AMO) at major universities throughout America. AMO concerns the study of matter-matter and light-matter interactions at the scale of one or a few atoms. The stated objectives of the Institute are:
