摘要：
Density waves in cigar-shaped dipolar Bose-Einstein condensates are analysed by variational means and we show analytically how the dipole-dipole interaction between the atoms generates a roton-maxon excitation spectrum. A simple model is used to derive the effective equations which describe the emergence of the density waves.
