Using the composite fermion transformation, one finds that the edge states of the $\\nu=1/m$ system in a disc sample are described by, in one dimensional limit, the Calogero-Sutherland model with other interactions between the composite fermions as perturbations. It is shown that a large class of short-range interactions renormalize only the Fermi velocity while the exponent $g=\\nu=1/m$ is invariant under the condition of chirality. By taking the sharp edge potential into account, we obtain a microscopic justification of the chiral Luttinger liquid model of the fractional quantum Hall edge states. The approach applied to the $\\nu=1/m$ system can be generalized to the other edge states with odd denominator filling factors.", "revisions": [ { "version": "v1", "updated": "1997-09-02T06:33:57.000Z" } ], "analyses": { "keywords": [ "chiral luttinger liquid", "composite fermion theory", "microscopic picture", "fractional quantum hall edge states" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
