Atomic, Molecular and Optical Physics
Atomic Physics studies about the structure of atoms, their mutual interaction and their dynamics, i.e., their time-dependent properties. The goal of experimental and theoretical efforts in this field is the full understanding of macroscopic properties of matter on the base of its microscopic composition of the constituent atoms and a quantitative description of the relations between microscopic and macroscopic features. Optical physics studies the interactions of light with atoms, molecules and semiconductor systems in different contexts. Research in optical physics places an emphasis on ultrafast optical science and technology. Researchers in optical physics use and develop light sources that span the electromagnetic spectrum from microwaves to X-rays. The applications of optical physics create innovations in communications, medicine, manufacturing, and even entertainment.
Atomic physics studies atoms as an isolated system of electrons and an atomic nucleus, while molecular physics is the study of the physical properties of molecules. The term atomic physics is frequently related with nuclear power and nuclear bombs, due to the synonymous use of atomic and nuclear in standard English. Molecular physics, while strictly related to atomic physics, also overlaps significantly with theoretical chemistry, physical chemistry and chemical physics. Optical physics is a part of atomic, molecular, and optical physics, dealing with the generation of electromagnetic radiation, the effects of that radiation, and the interaction of that radiation with matter, particularly its manipulation and control. It varies from general optics and optical engineering in that it is focused on the innovation and application of new phenomena. Conferences on Optics usually describes the behaviour of visible, ultraviolet, and infrared light used in imaging. Because light is an electromagnetic wave, alike phenomena occur in X-rays, microwaves, radio waves.
