Short range correlations in a one dimensional electron gas
We use the SSTL (Singwi, Sjölander, Tosi, Land) approximation to investigate the short–range correlations in a one dimensional electron gas, for the first time. Although SSTL is introduced to better satisfy the compressibility sum rule in three dimensions, we show that the widely used STLS (Singwi, Tosi, Land, Sjölander) approximation is more successful in the case of the one dimensional electr...
متن کاملSpin Correlation Effects In a One Dimensional Electron Gas
The Singwi, Sjölander, Tosi, Land (SSTL) approach is generalized to study the spin–correlation effects in a one dimensional electron gas. It is shown that the SSTL approach is capable of generating results comparable to the more widely used STLS approach. e-mail: [email protected] e-mail: [email protected]
متن کاملPossible Spin Polarization in a One-Dimensional Electron Gas.
In zero magnetic field, conductance measurements of clean one-dimensional (1D) constrictions defined in GaAs/AlGaAs heterostructures show twenty-six quantized ballistic plateaux, as well as a structure close to 0.7(2e 2 /h). In an in-plane magnetic field all the 1D subbands show Zeeman splitting and in the wide channel limit the g-factor is | g |= 0.4, close to that of bulk GaAs. For the last s...
متن کاملCalculation of Quasi-one-dimensional Interacting Electron Gas Using the Hartree-Fock Method
In this paper, the Hartree-Fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. The bare coulomb interaction between electrons has been assumed. For this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...
متن کاملSpin resolved energy parametrization of a quasi-one-dimensional electron gas
By carrying out extensive lattice regularized diffusion Monte Carlo calculations, we study the spin and density dependence of the ground state energy for a quasi-one-dimensional electron gas, with harmonic transverse confinement and long-range 1/r interactions. We present a parametrization of the exchangecorrelation energy suitable for spin density functional calculations, which fulfills exact ...
