electronic correlation energy
1Electronic correlation — refers to the interaction between electrons in a quantum system whose electronic structure is being considered. The term correlation stems from mathematical statistics and means that two distribution functions, f and g , are not independent of… …
2Electronic band structure — In solid state physics, the electronic band structure (or simply band structure) of a solid describes ranges of energy that an electron is forbidden or allowed to have. It is due to the diffraction of the quantum mechanical electron waves in the… …
