lattice axis
1Lattice (group) — A lattice in the Euclidean plane. In mathematics, especially in geometry and group theory, a lattice in Rn is a discrete subgroup of Rn which spans the real vector space Rn. Every lattice in Rn …
2axis — axis1 axised /ak sist/, adj. /ak sis/, n., pl. axes /ak seez/. 1. the line about which a rotating body, such as the earth, turns. 2. Math. a. a central line that bisects a two dimensional body or figure. b. a line about which a three dimensional… …
3Screw axis — The screw axis (helical axis or twist axis) of an object is a parameter for describing simultaneous rotation and translation components of that object.The axis is a directed line in space, along which a translation may occur, and about which… …
4Reciprocal 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… …
5Optical 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… …
6screw axis — Crystall. a symmetry element of a space group such that a rotation of the lattice about the axis and a translation of the lattice some fraction of the lattice s unit distance brings the lattice back to its original position. [1900 05] * * * …
7screw axis — Crystall. a symmetry element of a space group such that a rotation of the lattice about the axis and a translation of the lattice some fraction of the lattice s unit distance brings the lattice back to its original position. [1900 05] …
8Optic axis of a crystal — For the axis of an optical system, see Optical axis. The optic axis of a crystal is the direction in which a ray of transmitted light suffers no birefringence (double refraction). Due to the internal structure of the crystal (the specific… …
9screw axis — /ˈskru æksəs/ (say skrooh aksuhs) noun an axis of symmetry about which the atoms in a crystal lattice are arranged …
10Crystal structure of boron-rich metal borides — Two single crystals of YB66 (1 cm diameter) grown by floating zone technique using (100) oriented seeds. In the top crystal, the seed (left from the black line) has same diameter as the crystal. In the bottom crystal (sliced), the seed is much… …
