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