摘要:

我们使用双色晶格来打破玻色子87 Rb原子莫特绝缘体的均匀占位。我们通过对飞行时间后原子密度分布的噪声相关分析检测有序Mott域的破坏。额外的相关峰的出现证明了原子的重新分布成一个强烈的不均匀的绝缘状态,在定量上与预测一致。

英文摘要:

We use a two-color lattice to break the homogeneous site occupation of an atomic Mott Insulator of bosonic 87Rb. We detect the disruption of the ordered Mott domains via noise correlation analysis of the atomic density distribution after time-of-flight. The appearance of additional correlation peaks evidences the redistribution of the atoms into a strongly inhomogeneous insulating state, in quantitative agreement with the predictions.
