Cover: Dark solitons are localized defects in defocusing systems, and manifest themselves in repulsive Bose–Einstein condensate as a notch in the condensate density and a phase jump across the center. Ring dark solitons are candidates for observing long-time behaviors of 2D dark solitons, and their relevant explorations in the Bose–Einstein condensate began in 2003. It was shown that deeper ring dark solitons inclined to suffer snaking instabilities with a lifetime less than 20 milliseconds. In spinor Bose-Einstein condensates, however, ring dark solitons show more favorable stability comparing to that in scalar Bose–Einstein condensates. The deepest ring dark soliton can enjoy a lifetime of more than 40 milliseconds before decaying into four vortex and anti-vortex pairs. In addition, it can be found that the ring dark soliton in 87Rb condensate lives about 12 milliseconds longer than that in 23Na condensate, and this should be ascribed to the different spin-dependent interactions for these two kinds of condensates. The following dynamics of the vortex and anti-vortex pairs shows periodical oscillations, which is a common characteristic between 23Na and 87Rb condensates. For more detailed information, please refer to the article “Ground states, solitons and spin textures in spin-1 Bose–Einstein condensates” by Shu-Wei Song et al., pp 302–318.
