- Abstract
We study the existence and stability of the bound state Josephson vortices solution in two parallel quasi one-dimensional coupled Bose-Einstein condensates. The system can be elucidated by linearly coupled Gross-Pitaevskii equations. The purpose of this study is to investigate the effects of altering the strength of coupling between the two condensates over the stability of the bound-state Josephson vortices. It is found that the stability of bound-state Josephson vortices depends on the value of coupling strength. However, at a critical value of coupling parameter, the Josephson vortices solution transforms into a coupled dark soliton.
