Abstract

We construct model wave functions for a family of single-quasielectron states supported by the ν=1/3 fractional quantum Hall fluid. The charge e*=e/3 quasielectron state is identified as a composite of a charge-2e* quasiparticle and a -e* quasihole, orbiting around their common center of charge with relative angular momentum nâ >0, and corresponds precisely to the "composite fermion" construction based on a filled n=0 Landau level plus an extra particle in level n>0. An effective three-body model (one 2e* quasiparticle and two -e* quasiholes) is introduced to capture the essential physics of the neutral bulk excitations.
