摘要：
In this short note, we investigate by variational means the emergence of Faraday waves in cigar-shaped Bose-Einstein condensates with radially inhomogeneous scattering lengths subject to periodic modulations of the radial confining potential. Our main result is that for weakly inhomogeneous scattering lengths, the Faraday waves follow a dispersion relation identical to that observed in condensates with spatially homogeneous scattering lengths.
