Nonperiodic oscillation of bright solitons in the condensates with a
periodically oscillating harmonic potential

Z. M. He, D. L. Wang, Y. C. She, J. W. Ding
Considering a periodically oscillating harmonic potential, we explore the
dynamics properties of bright solitons in a Bose-Einstein condensate. It is
found that under a slower oscillating potential, soliton movement exhibits a
nonperiodic oscillation while it is hardly affected under a fast oscillating
potential. Furthermore, the head-on and/or "chase" collisions of two solitons
have been obtained, which can be controlled by the oscillating frequency of
