Phys. Rev. A 78, 043613 (2008) [6 pages]Faraday waves in elongated superfluid fermionic cloudsReceived 8 August 2008; published 23 October 2008 We use hydrodynamic equations to study the formation of Faraday waves in a superfluid Fermi gas at zero temperature confined in a strongly elongated cigar-shaped trap. First, we treat the role of the radial density profile in the limit of an infinite cylindrical geometry and analytically evaluate the wavelength of the Faraday pattern. The effect of the axial confinement is fully taken into account in the numerical solution of hydrodynamic equations, and shows that the infinite cylinder geometry provides a very good description of the phenomena. © 2008 The American Physical Society URL:
