| 摘 要： | We present both the bright and dark solitons of Bose-Einstein condensates with a time-dependent atomic scattering length in an expulsive parabolic potential. As a discussed example, we select the experimental parameter, i.e. the Feshbach-managed nonlinear coefficient reading a(t) = go exp(λt), and obtain the results which can be recovered in the literature Phys. Rev. Lett. 94 (2005) 050402].
