2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/16867We comment on the recent paper by Scarola, Park, and Jain [Nature v. 406, p. 863 (2000); cond-mat/0012030] on a trial wavefunction calculation of pairing in a fractional quantum Hall system at nu=5/2. We point out two errors that invalidate the claimed calculations of a binding energy for Cooper pairs and of an energy gap for charged excitations.3 pages, RevTeX, not submitted to Nature.
