First-Order Density Matrix, Pair-Distribution Function And Structure Factor of a Fermi Liquid

Abstract

Where overlap exists, results of the free Fermi gas in D dimensions agree between the studies of Lee and Long [Phys, Rev., E, 52, 189 (1995)] and our own previous works. We add some results of the effect of intractions in the three-dimensional electron liquid phase relating to the first-order density matrix, the electron-pair function, and the structure factor.

Key Words:

• Fermi liquid
• density matrix
• structure factor
• pair distribution
