Self-Consistent Local-Field Corrections and Structure Factors in a Spin-Polarized Electron Gas
نویسندگان
چکیده
We investigated self-consistent spin-resolved local-field corrections in a spin-polarized electron gas. The local-field corrections, structure factors, and susceptibility functions form a self-consistent loop. Three different local-field corrections and structure factors each based on the Hartree-Fock structure factor, the Gori-Giorgi–Perdew pair correlation function, and self-consistent calculation are discussed. We find that the local-field corrections G↑↓(q) and G↓↑(q) describing anti-parallel spin correlations in the spin-polarized electron gas are finite, but different from each other, while in the Hartree-Fock approximation they vanish identically.

The Thermodynamic Properties of Polarized Metallic Nanowire in the Presence of Magnetic Field
In this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. We have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. The spin-polarization parameter corresponding to the equilibrium state of ...
متن کاملSpin-density functional approach to thermodynamic and structural consistence in the charge and spin response of an electron gas
We use spin-density functional theory to obtain novel expressions for the charge and spin local-field factors of an electron gas in terms of its electron-pair structure factors. These expressions (i) satisfy the compressibility and spin susceptibility sum rules; (ii) keep account of kinetic correlations by means of an integration over the coupling strength; and (iii) provide a practical self-co...

We investigate the charge and spin response functions of a bilayer quasi-two-dimensional system, spin polarized by a constant magnetic field BW . Terms beyond the random-phase approximation, the exchange and correlation interactions, are introduced by using generalized spin-dependent local field factors, Gs x (qW ,v). The self-consistent magnetic interaction among the electron spins determines ...

The spontaneous spin polarization of a quantum point contact (QPC) formed by the lateral confinement of a highmobility two-dimensional electron gas in a GaAs/AlGaAs split gate heterostructure is investigated. Self consistent calculations of the electronic structure of the QPC are performed using the spin-polarized density functional formalism of Kohn and Sham. Spin polarization occurs at low el...
متن کاملFinite width and local field corrections to spin coulomb drag in a quasi-two-dimensional electron gas.
We study the spin Coulomb drag in a quasi-two-dimensional electron gas of finite transverse width, including local field corrections beyond the random phase approximation (RPA). We find that the finite transverse width of the electron gas causes a significant reduction of the spin Coulomb drag. This reduction, however, is largely compensated by the enhancement coming from the inclusion of many-...
