Comment on "Cooper instability of composite fermions"
Abstract
We 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.
