Irregular Spin Tunnelling for Spin-1 Bose-Einstein Condensates in a Sweeping Magnetic FieldNov 29 2006We investigate the spin tunnelling of spin-1 Bose-Einstein condensates in a linearly sweeping magnetic field with a mean-field treatment. We focus on the two typical alkali Bose atoms $^{87}Rb$ and $^{23}Na$ condensates and study their tunnelling dynamics ... More
Periodic Modulation Effect on Self-Trapping of Two weakly coupled Bose-Einstein CondensatesSep 22 2005With phase space analysis approach, we investigate thoroughly the self-trapping phenomenon for two weakly coupled Bose-Einstein condensates (BEC) in a symmetric double-well potential. We identify two kinds of self-trapping by their different relative ... More
Classical collisional trajectories as the source of strong-field double ionization of helium in the knee regimeDec 05 2001In this paper, a quasistatic model is extended to describe the double ionization of Helium in intense linearly polarized field, yielding achieve an insight to the two-electron correlation effect in the ionization dynamics. Our numerical calculations reproduce ... More
