Nature of Quasielectrons and the Continuum of Neutral Bulk Excitations in the Laughlin Quantum Hall Fluids (1308.4920v2)
Published 22 Aug 2013 in cond-mat.str-el
Abstract: We construct model wavefunctions for a family of single-quasielectron states supported by the $\nu=1/3$ fractional quantum Hall (FQH) 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 $n\hbar > 0$, 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.
