antiferromagnetic
31Crystal — /kris tl/, n. 1. a city in SE Minnesota, near Minneapolis. 25,543. 2. a female given name. * * * I Any solid material whose atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. Each of a crystal s… …
32antiferromagnetism — ▪ physics type of magnetism (ferromagnetism) in solids such as manganese oxide (MnO) in which adjacent ions that behave as tiny magnets (in this case manganese ions, Mn2+) spontaneously align themselves at relatively low temperatures into… …
33Magnetism — This article is about magnetic materials. For information about objects and devices that produce a magnetic field, see magnet. For fields that magnets and currents produce, see magnetic field. For other uses, see magnetism (disambiguation).… …
34Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
35Geometrical frustration — is a phenomenon in condensed matter physics in which the geometrical properties of the atomic lattice forbid the existence of a unique ground state, resulting in a nonzero residual entropy. The most important consequence of this is that the… …

37Mott insulator — Mott insulators are a class of materials that should conduct electricity under conventional band theories, but are insulators when measured (particularly at low temperatures). This effect is due to electron electron interactions which are not… …
38QMR effect — Quadratic Magnetic Rotation of Polarization of Light is called also QMR or QMR effect.QMR is a type of magneto optic effect, discovered in the mid 1980 s by a team of Ukrainian physicists. QMR, like the Faraday effect, establishes a relationship… …
39Mottness — In condensed matter physics, mottness is a term which denotes the additional ingredient, aside from antiferromagnetic ordering, which is necessary to fully describe a Mott Insulator. In other words, we might write: antiferromagnetic order +… …
40Dmrg of Heisenberg model — This example presents the infinite DMRG algorithm. It is about S = 1 antiferromagnetic Heisenberg chain, but the recipe can be applied for every translationally invariant one dimensional lattice. DMRG is a renormalization group technique because… …
