local density approximation
1Local-density approximation — The local density approximation (LDA) is an approximation of the exchange correlation (XC) energy functional in density functional theory (DFT) by taking the XC energy of an electron in a homogeneous electron gas of a density equal to the density …

6Distortion free energy density — The Distortion free energy density is a quantity that describes the distortion of a liquid crystal from its preferred state in which all of the liquid crystal molecules are aligned parallel to one common axis. It also commonly goes by the name… …
7Relative density — Relative density, sometimes called specific density, is the ratio of the density of a substance to the density of a given reference material. If a substance s relative density is less than one then it is less dense than the reference; if greater… …
8Current density — This page is about the electric current density in electromagnetism. For the probability current density in quantum mechanics, see Probability current. Current density is a measure of the density of flow of a conserved charge. Usually the charge… …
