Optical lattice — Simulation of an optical lattice potential. An optical lattice is formed by the interference of counter propagating laser beams, creating a spatially periodic polarization pattern. The resulting periodic potential may trap neutral atoms via the… … Wikipedia
Fokker periodicity blocks — are a concept in tuning theory used to mathematically relate musical intervals in just intonation to those in equal tuning. They are named after Adriaan Daniël Fokker.The basic idea of Fokker s periodicity blocks is to represent just ratios as… … Wikipedia
Reciprocal lattice — In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum… … Wikipedia
Crystallographic restriction theorem — The crystallographic restriction theorem in its basic form was based on the observation that the rotational symmetries of a crystal are usually limited to 2 fold, 3 fold, 4 fold, and 6 fold. However, quasicrystals can occur with other symmetries … Wikipedia
Order and disorder (physics) — In physics, the terms order and disorder designate the presence or absence of some symmetry or correlation in a many particle system. In condensed matter physics, systems typically are ordered at low temperatures; upon heating, they undergo one… … Wikipedia
