Comment on "Pairing and Phase Separation in a Polarized Fermi Gas"

Martin W. Zwierlein and Wolfgang Ketterle^*

Partridge et al. (Reports, 27 January 2006, p. 503) reportedpairing and phase separation in a polarized Fermi gas. We arguethat it is not possible to distinguish the superfluid from thenormal regimes in the presented data, or to discern which cloudswere phase-separated. Some of the reported conclusions are inconsistentwith recent experiments.
