论文摘要
从理论上讲，我们研究了两个相互作用的超速磁性原子的特性，这些原子被困在一维谐波电位中。原子通过各向异性远程偶极双极相互作用相互作用，该偶极相互作用可以通过接触相互作用有效地建模。我们研究了外部磁场的相互作用，自旋旋转相互作用及其诱捕势以及它们如何影响系统的磁化。我们通过研究可以通过实验测量的可观察到的时间演变来展示无法区分性和对称性在动力学中的作用。提出的模型可以描述扩展哈伯德模型的现场相互作用，因此可以更好地了解各个多体量子模拟器的基本构建块。
We theoretically investigate the properties of two interacting ultracold highly magnetic atoms trapped in a one-dimensional harmonic potential. The atoms interact via an anisotropic long-range dipole-dipole interaction, which in one dimension effectively can be modeled by the contact interaction. We investigate the interplay of the external magnetic field, the spin-spin interaction, and the trapping potential and how they affect the magnetization of the system. We show the role of indistinguishability and symmetries in the dynamics by studying the time evolution of the observables that could be measured experimentally. The presented model may depict the on-site interaction of the extended Hubbard models, therefore giving a better understanding of the fundamental building block of the respective many-body quantum simulators.
