Anisotropic charge density waves in the electron gas

Abstract

The analysis of the formation of anisotropic charge density waves for an electron gas system embedded in a deformable jellium model at finite temperature is presented. The formulation of the problem is based on unrestricted temperature-dependent Hartree-Fock equations. In the present work we focus our discussion in studying the instability condition against the formation of 3D anisotropic charge density waves. The phase diagram for different values of the anisotropy parameter is constructed and zones of stability are shown.
