Comment on "Cooper instability of composite fermions"
msra(2000)
摘要
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.
