Mean-field model of interaction between bright vortex solitons in Bose-Einstein condensates | Sadhan K. Adhikari

6 Jul 2002 | Journal: | New J. Phys. 5 (2003) 137 (1-13) | Subject: | Soft Condensed Matter; Pattern Formation and Solitons | cond-mat.soft nlin.PS | Abstract: | Using the explicit numerical solution of the axially-symmetric Gross-Pitaevskii equation we study the dynamics of interaction among vortex solitons in a rotating matter-wave bright soliton train in a radially trapped and axially free Bose-Einstein condensate to understand certain features of the experiment by Strecker et al.[2002 Nature 417 150]. In a soliton train, solitons of opposite phase (phase delta = pi) repel and stay apart without changing shape; solitons with delta = 0 attract, interact and coalesce, but eventually come out; solitons with a general delta usually repel but interact inelastically by exchanging matter. We study and suggest future experiments with vortex solitons. | Source: | arXiv, cond-mat/0207171 | Services: | Forum | Review | PDF | Favorites |
