AI Article Synopsis
- The study investigates solitary wave behavior in a cylindrical Bose-Einstein trap, revealing a hybrid structure combining 1D soliton and 3D vortex ring characteristics.
- The analysis focuses on conditions with strong couplings that are relevant to current experiments.
- The energy-momentum dispersion shows similarities to a previously proposed 1D mode by Lieb, while also exhibiting roton-like features.
Article Abstract
We present a calculation of a solitary wave propagating along a cylindrical Bose-Einstein trap. For sufficiently strong couplings of experimental interest, it is found to be a hybrid of a one-dimensional (1D) soliton and a three-dimensional vortex ring. The calculated energy-momentum dispersion exhibits characteristics similar to those of a mode proposed sometime ago by Lieb within a 1D model, as well as some rotonlike features.
