| Abstract: | We present the results of the theoretical analysis of quasi one-dimensional electron gas within the Hartree–Fock approximation. The ground state energy for full polarized and unpolarized states is calculated at T = 0. The formation of spontaneously spin-polarized state at low linear concentration of electrons and its transformation to unpolarized state as concentration increases is discussed. |
