Abstrak

The work by T. K. Ghosh and K. Machida [ cond-mat/0510160 and Phys. Rev. A 73 , 013613 (2006)] on the sound velocity in a cylindrically conﬁned Fermi superﬂuid obeying a power-law equation of state is shown to make use of an improper projection of the sound wave equation. This inaccuracy fully accounts for the diﬀerence between their results and those previously reported by Capuzzi et al. [ cond-mat/0509323 and Phys. Rev. A 73 , 021603(R) (2006)]. In this Comment we show that both approaches lead exactly to the same result when the correct weight function is used in the projection. Plots of the correct behavior of the phonon and monopole-mode spectra in the BCS, unitary, and BEC limits are also shown.
