RKKY range function of a one-dimensional noninteracting electron gas
The apparently straightforward evaluation of the Ruderman-Kittel-Kasuya-Yosida RKKY range function, or more generally, of the linear density modulation n x induced at zero temperature in a noninteracting onedimensional electron gas by a localized static impurity modeled with a function potential has proven surprisingly troublesome. Although the original calculation gave an incorrect answer,1 mo...
متن کاملShort 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 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 کاملMany-body effects in a two-component, one-dimensional electron gas with repulsive, short-range interactions
We investigate the correlation effects in a two-component, one-dimensional electron gas interacting via repulsive 6 function interactions. Electron correlations are treated within the approximation scheme of Singwi, Tosi, Land, and SjGlander (STLS) which yields analytical expressions for the local-field corrections. The static structure factors, pair distribution functions, collective excitatio...
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]
