The jellium model - Big Chemical Encyclopedia

Jellium, also known as the uniform electron gas (UEG) or homogeneous electron gas (HEG), is a quantum mechanical model of interacting electrons in a solid where the positive charges (i.e. atomic nuclei) are assumed to be uniformly distributed in space; the electron density is a uniform quantity as well … Visualizza altro The jellium model treats the electron-electron coupling rigorously.
