Abstract
A microscopic construction of the chiral boson edge field theory for neutral and charged excitations of generalized Laughlin's states in smooth confining potentials for two-edge geometries is described. This is done by taking account of the topological degrees of freedom of the two chiral fields, which obey a joint constraint due to overall neutrality. This establishes a thorough correspondence with some traits of the heterotic string construction. © 1998 Elsevier Science B.V.File in questo prodotto:
