Webcui si basa l’ipotesi di Wigner è il jellium, ovvero il gas di elettroni immerso in una carica di background continua e positiva, di densità pari a quella elet-tronica: il sistema è quindi neutro e, almeno ad alte densità, omogeneo ed invariante per traslazioni. Riducendo la densità del gas (anche il background http://wwwteor.mi.infn.it/~molinari/TESI/Antonelli.pdf

Simple approach to treat interacting electrons by neglecting the ion lattice structure considering the positive charges as a background Originally introduced to describe electronic properties of simple metals Assumptions: ions are single positively charged constant lattice potential ion density is spatially independent ... WebThe Jellium model of Wigner (Ichimaru, 1982; March and Tosi, 1984; Martin, 1988; Singwi and Tosi, 1981) is an assembly of N+ spin up pointwise electrons and N− spin down … the way of life 歌詞

WebA Hydrogen atom immersed in a finite jellium sphere is solved using variational quantum Monte Carlo (VQMC). The same system is also solved using density ... The immersion energies calculated using these methods, as functions of the background density of the jellium, are found to lie within 1eV of each other with minima in approximately the same ...

English Wikipedia has an article on: jellium. … WebFreysoldt's scheme is a common approach. The basic idea is that you use a simple model to describe the defect's charge, such that you can calculate it's isolated energy interacting with the jellium background, as well as the energy of a periodic system that is interacting with it's images, using Poisson's equation. the way of love book
