Lieb mode in a quasi-one-dimensional Bose-Einstein condensate of atoms

Jackson, AD and Kavoulakis, Georgios LU (2002) In Physical Review Letters 89(7).
Abstract
We calculate the dispersion relation associated with a solitary wave in a quasi-one-dimensional Bose-Einstein condensate of atoms confined in a harmonic, cylindrical trap in the limit of weak and strong interactions. In both cases, the dispersion relation is linear for long-wavelength excitations and terminates at the point where the group velocity vanishes. We also calculate the dispersion relation of sound waves in both limits of weak and strong coupling.
