Home > Atomic, molecular, and optical physics

Molecular physics focuses on multi-atomic structures and their internal and external interactions with matter and light.

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.

All three areas include both classical and quantum treatments.

Atomic numberThe atomic number Z is a term used in chemistry and physics to represent the number of protons found in the nucleus of an atom. In an atom of neutral charge, the number of electrons typically equals the atomic number. The atomic number originally meant th AtomicThe general meaning of "atomic" is "irreducible". That is, reduced to the smallest possible part. It has more specific meanings in several contexts: In chemistry, chemical atoms are grouped by type in the periodic table and consist of particles as describ Atomic physicsAtomic physics (or atom physics is physics of the electron hull of atoms. Lay people often associate the term atomic physics with nuclear power and nuclear bombs, obviously due to the synonymous use of atomic and nuclear in standard English. However, phys Atomic orbitalAn atomic orbital is the mode of behavior of an electron in an atom (see first Electron orbital).

Atomic semantics are defined for a variable with a single writer but mu Atomic clockAn atomic clock is a type of clock that uses an atomic frequency standard as its counter. Early atomic clocks were masers with attached equipment.
