Mott phase
The theory was first proposed by Nevill Francis Mott in a 1949 paper. Mott also wrote a review of the subject (with a good overview) in 1968. The subject has been thoroughly reviewed in a comprehensive paper by Imada, Fujimori and Tokura. A recent proposal of a "Griffiths-like phase close to the Mott transition" has been reported in the literature.
