abstract = {<p style="text-align: justify;">The dynamics and interaction of quantized vortices in Bose-Einstein condensates
(BECs) are investigated by using the two-dimensional Gross-Pitaevskii equation
(GPE) with/without an angular momentum rotation term. If all vortices have the
same winding number, they would rotate around the trap center but never collide. In
contrast, if the winding numbers are different, their interaction highly depends on the
initial distance between vortex centers. The analytical results are presented to describe
the dynamics of the vortex centers when β=0. While if β≠0, there is no analytical result
but some conclusive numerical findings are provided for the further understanding of
vortex interaction in BECs. Finally, the dynamic laws describing the relation of vortex
interaction in nonrotating and rotating BECs are presented.</p>},
