论文摘要
我们提出了一项建议，以实现具有强烈相互作用的冷原子的一维临界旋转系统中的纠缠哈密顿量。我们的方法基于这样的观念：这种系统的纠缠谱可以用包含一组依赖位置的耦合的物理哈密顿量实现。我们专注于在两个不同的几何形状中重现系统的纠缠谱的通用比率：一个谐波陷阱，它与无限系统中嵌入的分区相对应，以及线性电势，该势能将半分配的特性带有开放边界条件。我们的结果表明，通过简单地使用重力和标准捕获技术，在现实的冷原子实验环境中测量海森堡和XX模型的纠缠光谱的可能性。
We present a proposal for the realization of entanglement Hamiltonians in one-dimensional critical spin systems with strongly interacting cold atoms. Our approach is based on the notion that the entanglement spectrum of such systems can be realized with a physical Hamiltonian containing a set of position-dependent couplings. We focus on reproducing the universal ratios of the entanglement spectrum for systems in two different geometries: a harmonic trap, which corresponds to a partition embedded in an infinite system, and a linear potential, which reproduces the properties of a half-partition with open boundary conditions. Our results demonstrate the possibility of measuring the entanglement spectra of the Heisenberg and XX models in a realistic cold-atom experimental setting by simply using gravity and standard trapping techniques.
