Correlation energy and the virial theorem

Abstract

Le theoreme du viriel 2E K +E p =3PV, ou P est la pression et V le volume, est connu pour etre valable pour les particules ponctuelles a interactions coulombiennes. On admet souvent qu'il est valable pour les electrons dans un fond de Jellium rigide, mais il n'est pas evident que ce soit le cas. On montre que le theoreme du viriel est valable, etant donne que l'energie de correlation possede la forme dimensionnellement correcte e 4 f(e 2 v s ), ou f est une fonction arbitraire en unites Ry, v s etant le rayon de la sphere electronique en bohrs, et e 2 =1 la constante de couplage sans dimension
