Encyclopedia > Atomic, molecular, and optical physics

Atomic, molecular, and optical physics is the study of matter-matter and light-matter interactions on the scale of single atoms or structures containing a few atoms. The three areas are grouped together because of their interrelationships, the similarity of methods used, and the commonality of the energy scales that are relevant. Physicists sometimes abbreviate the field as AMO physics. Properties For alternative meanings see atom (disambiguation). ... A molecule is something that Lelea has in her room in Chase. ... See also list of optical topics. ... Since antiquity, people have tried to understand the behavior of matter: why unsupported objects drop to the ground, why different materials have different properties, and so forth. ... Matter is commonly referred to as the substance of which physical objects are composed. ... Prism splitting light Light is electromagnetic radiation with a wavelength that is visible to the eye or, in a technical or scientific setting, electromagnetic radiation of any wavelength. ... Properties For alternative meanings see atom (disambiguation). ...


Atomic physics is distinct from nuclear physics, despite their association in the public consciousness. Atomic physics is not concerned with the intra-nuclear processes studied in nuclear physics, although properties of the nucleus can be important in atomic physics (e.g., hyperfine structure). Atomic physics (or atom physics) is physics of the electron hull of atoms. ... Nuclear physics is the branch of physics concerned with the nucleus of the atom. ... In atomic physics, hyperfine structure is a small perturbation in the energy levels (or spectrum) of atoms or molecules due to the magnetic dipole-dipole interaction, arrising from the interaction of the nuclear magnetic dipole with the magnetic field of the electron. ...


Molecular physics focuses on multi-atomic structures and their internal and external interactions with matter and light. Molecular physics is the study of the physical properties of molecules and of the chemical bonds between atoms that bind them into molecules. ...


Optical physics is distinct from optics in that it tends to focus not on the control of classical light fields by macroscopic objects, but on the fundamental properties of optical fields and their interactions with matter in the microscopic realm. See also list of optical topics. ...


All three areas include both classical and quantum treatments. Classical physics is physics based on principles developed before the rise of quantum theory, including the special theory of relativity. ... Fig. ...
