Mott 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… … Wikipedia
Mottness — 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 +… … Wikipedia
