我们提出了一个在几十微秒内将玻色-爱因斯坦凝聚体非相干地加载到一维光晶格基态的方案，即，通常在不到塔尔博特时期的一半。这种相干控制技术是基于脉冲扰动序列的，实验结果证明了它的可行性和有效性。由于加载过程比传统的绝热加载时间尺度短得多，因此该方法具有广泛的应用前景。
We present a scheme for nonadiabatically loading a Bose-Einstein condensate into the ground state of a one-dimensional optical lattice within a few tens of microseconds, i.e., typically in less than half the Talbot period. This technique of coherent control is based on sequences of pulsed perturbations, and the experimental results demonstrate its feasibility and effectiveness. As the loading process is much shorter than the traditional adiabatic loading time scale, this method may find many applications.
