One Dimensional Interacting Fermion System By Daya Koyira

Some properties of metals at a low - lying excitation is studied analytically basedrnon the theory of Fermi liquid. The breakdown of Landau’s theory of Fermi liquid inrnone dimension is analyzed. The one dimensional interacting system shows the powerrnlaw behavior and logarithmic divergence in its correlation function. In contrast, thernFermi liquid shows the pole in its microscopic equation of the Green’s function
