    "abstract": "Recently, the splitting of a topologically created doubly quantized vortex\ninto two singly quantized vortices was experimentally investigated in dilute\natomic cigar-shaped Bose-Einstein condensates [Y. Shin et al., Phys. Rev. Lett.\n93, 160406 (2004)]. In particular, the dependency of the splitting time on the\npeak particle density was studied. We present results of theoretical\nsimulations which closely mimic the experimental set-up. Contrary to previous\ntheoretical studies, claiming that thermal excitations are the essential\nmechanism in initiating the splitting, we show that the combination of\ngravitational sag and time dependency of the trapping potential alone suffices\nto split the doubly quantized vortex in time scales which are in good agreement\nwith the experiments. We also study the dynamics of the resulting singly\nquantized vortices which typically intertwine--especially, a peculiar vortex\nchain structure appears for certain parameter values.",
