NONAUTONOMOUS DARK SOLITONS IN BOSE-EINSTEIN CONDENSATE.

In this paper, we study on dark solitons of Bose-Einstein condensate analytically in a time-dependent harmonic trap with an arbitrary time-dependent linear potential and complex potential. It is shown that the nonautonomous dark soliton can be manipulated well through managing external potentials and nonlinear interaction between atoms. We believe that these results would stimulate experiments to manage dark solitons. [ABSTRACT FROM AUTHOR]
