Important material properties can be explained at the level of quantum physics - for example, whether a material conducts electricity or not. Analysing such quantum states has now revealed that there ...

Noble gases such as helium and neon are poor conductors of electricity, so we call them electrical insulators ... valence band (that is, the energy embodied in the highest-energy electron that ...

This peculiar behavior stems from strong electron-electron ... Concept of a Mott-insulator (center) along with its bandfilling-controlled (left) and bandwidth-controlled (right) Mott transitions. When ...

Certain energy ... conductors and insulators than previously thought." More information: Juraj Krsnik et al, Local correlations necessitate waterfalls as a connection between quasiparticle band ...

The observation of a Mott transition from a metal to an insulator ... It has one valence electron per unit cell, so the lowest band is half-filled and the maximum electron energy — also known ...
