  In this paper, we present a description of Haldane's Luttinger liquid which
parallels Laughlin's theory of the Fractional Quantum Hall (FQH) incompressible
fluid, both exhibiting similar ground states as well as fractional excitations.
These two non-Fermi liquids are instances of a generic structure for
low-dimensional quantum liquids which we propose to dub Jastrow-Luttinger
Fractional Liquids. An important feature of such liquids is the complete
fractionalization of the parent particle. In particular, in both one and two
dimensions spin-charge separation can be achieved and is indeed suggested to
occur for unpolarized quantum Hall systems both at the edge and in the bulk.
