论文摘要
在一个空间维度中，量子交换统计和相互作用是密不可分的。作为一种表现，tonks-girardeau气体的膨胀动力学的特征是动力学费用（DF），在这种情况下，动量分布接近自旋极化的费米气体的动量分布。使用相位空间分析和单体降低密度矩阵的统一演变，我们表明DF可以使用Delta Kick冷却（DKC）的概括来量身定制和逆转与交互系统进行介绍，从而建立了一种简单的协议来重新汇总初始动量分布。该协议既适用于扩展和压缩，又用于量子相关的显微镜。
In one spatial dimension, quantum exchange statistics and interactions are inextricably intertwined. As a manifestation, the expansion dynamics of a Tonks-Girardeau gas is characterized by dynamical fermionization (DF), whereby the momentum distribution approaches that of a spin-polarized Fermi gas. Using a phase-space analysis and the unitary evolution of the one-body reduced density matrix, we show that DF can be tailored and reversed, using a generalization of delta kick cooling (DKC) to interacting systems, establishing a simple protocol to rescale the initial momentum distribution. The protocol applies to both expansions and compressions and can be used for microscopy of quantum correlations.
