我们考虑耦合有限尺寸一维玻色气体的二维阵列的二维莫特绝缘体状态。结果表明，晶格平面中的动量分布对一维管中的相互作用状态非常敏感。特别是，我们发现飞行时间实验中干涉图案的消失是沿管的唐克斯-吉拉多体系强烈相互作用的明显结果。
We consider the 2D Mott-insulator state of a 2D array of coupled finite size 1D Bose gases. It is shown that the momentum distribution in the lattice plane is very sensitive to the interaction regime in the 1D tubes. In particular, we find that the disappearance of the interference pattern in time-of-flight experiments is a clear consequence of the strongly interacting Tonks-Girardeau regime along the tubes.
