摘要
We construct model wave functions for a family of single-quasielectron states supported by the nu = 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 n. > 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.
