Metal Insulator transition(MIT) is characterized by the conductivity which will be zero in the insulator phase. In this term paper, we focus on Mott insulator, and a simple theoritical way to describe this MIT is the Hubbard Model .Finally, we will look at the experiments of Mott insulator transition .

2014 Fe1+xNb3-xSe10 with x = 0.32, 0.38 and Cr1.45Nb2.55Se10 were prepared by heating in evacuated silica tubes. The structure was determined by Weissenberg photograph. The metal-insulator transition of Fe1+xNb3-xSe10 and of Cr1.45Nb2.55Se10 was studied by measurements of resistivity, and magnetic susceptibility. The metal-insulator transition is correlated with the CDW which depresses the cond...

Fundamental insight into the nature of the quantum phase transition from a superconductor to an insulator in two dimensions, or from one plateau to the next or to an insulator in the quantum Hall effect, has been revealed through the study of its scaling behavior. Here, we report on the experimental observation of a quantum phase transition from a quantum-anomalous-Hall insulator to an Anderson...

Magnetic fluctuations in transition metal oxides are a subject of intensive research because of the key role they are expected to play in the transition from the Mott insulator to the unconventional metallic phase of these materials, and also as drivers of superconductivity. Despite much effort, a clear link between magnetic fluctuations and the insulator-to-metal transition has not yet been es...

The effect of pressure on the metal–insulator transition in manganites with a broad range of bandwidths is investigated. A critical pressure is found at which the metal–insulator transition temperature, TMI , reaches a maximum value in every sample studied. The origin of this universal pressure and the relation between the pressure effect and the bandwidth on the metal–insulator transition are ...
