This chapter is intended as a brief overview of some of the quantum spin liquid phases with unbroken SU(2) spin symmetry available in one dimension. The main characteristics of these phases are discussed by means of the bosonization approach. A special emphasis is laid on the interplay between frustration and quantum fluctuations in one dimension. 1.

It is shown that Landau's mean field theory of Fermi liquids is valid in two-dimensional case through evaluation of the quasiparticle life-time of a 2-D interacting Fermi systems at low density as well as the spin fluctuation of 2-D itinerant Fermi systems.
