Özet

The Singwi-Sjolander-Tosi-Land (SSTL) approach is generalized to study the spin-correlation effects in a one-dimensional (1D) electron gas. It is shown that the SSTL approach yields different and interesting results compared with the more widely used Singwi-Tosi-Land-Sjolander (STLS) approach. We find out that the self-consistent field approaches, STLS and SSTL, predict a Bloch transition for 1D electron-gas systems at low electron densities.
