摘要:

分析了驻波脉冲序列对玻色-爱因斯坦凝聚体(BEC)的影响。实验观测与基于光晶格能带结构理论的数值模拟结果吻合良好。我们还证明了基于这种脉冲序列的相干控制方法对于实验设计特定的动量态是非常有效的。

英文摘要:

We analyze the effects of sequences of standing wave pulses on a Bose-Einstein condensate (BEC). Experimental observations are in good agreement with a numerical simulation based on the band structure theory in the optical lattice. We also demonstrate that a coherent control method based on such sequences of pulses is very efficient for experimentally designing specific momentum states.
