12Photon induced electric field poling — In physics, photon induced electric field poling is a phenomenon whereby a pattern of local electric field orientations can be encoded in a suitable ferroelectric material, such as perovskite. The resulting encoded material is conceptually… …
13geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… …
14Crystal field theory — (CFT) is a model that describes the electronic structure of transition metal compounds, all of which can be considered coordination complexes. CFT successfully accounts for some magnetic properties, colours, hydration enthalpies, and spinel… …
15Langston Field — The Langston Field is a fictional device featured in the CoDominium series of science fiction novels, initiated by SF writer Jerry Pournelle. The (fictional) Langston Field generator creates a spherical shield around an object (usually a… …
16Stellar magnetic field — A stellar magnetic field is a magnetic field generated by the motion of conductive plasma inside a main sequence (hydrogen burning) star. This motion is created through convection, which is a form of energy transport involving the physical… …
17ligand field theory — ▪ chemistry in chemistry, one of several theories that describe the electronic structure of coordination or complex compounds, notably transition metal complexes, which consist of a central metal atom surrounded by a group of electron rich… …
18quantum field theory — Physics. any theory in which fields are treated by the methods of quantum mechanics; each field can then be regarded as consisting of particles of a particular kind, which may be created and annihilated. [1945 50] * * * Theory that brings quantum …
19Relationship between string theory and quantum field theory — Many first principles in quantum field theory are explained, or get further insight, in string theory: * Emission and absorption: one of the most basic building blocks of quantum field theory, is the notion that particles (such as electrons) can… …
20Twisted nematic field effect — The twisted nematic effect ( TN effect ) in liquid crystals is claimed to be first discovered by James Fergason in 1970 at the International Liquid Xtal Company in Kent Ohio. Fergason patented his work at about the same time that the Central… …
