Dynamics of vector dark soliton induced by the Rabi coupling in one-dimensional trapped Bose-Einstein condensates

► We consider the Rabi coupling to affect the dark soliton in BECs. ► We examine the changes of the initial dark solitons. ► The structure of the soliton depends on the inter- and intraspecies interactions strength. ► The Rabi coupling can be used to obtain various vector dark solitons.
