论文摘要
我们提出了一种在二维晶格中量子链接模型的量子模拟方案。我们的方法考虑了适当形状的晶格上的旋转偶极气，其中不同超精美气体的颗粒动力学发生在与偶尔相互作用相连的一维链中。我们表明至少需要四个级别。本方案不需要对参数进行任何特定的微调。我们通过两种不同的方法，一种与角动量保护相关的非扰动和扰动的方法来执行量子链接模型的参数的推导。讨论了文献中存在的$（2+1）$ - 维量子链接模型的比较。最后，提出了三维晶格的延伸，并指出了其微妙之处。
We propose a scheme for the quantum simulation of quantum link models in two-dimensional lattices. Our approach considers spinor dipolar gases on a suitably shaped lattice, where the dynamics of particles in the different hyperfine levels of the gas takes place in one-dimensional chains coupled by the dipolar interactions. We show that at least four levels are needed. The present scheme does not require any particular fine-tuning of the parameters. We perform the derivation of the parameters of the quantum link models by means of two different approaches, a non-perturbative one tied to angular momentum conservation, and a perturbative one. A comparison with other schemes for $(2+1)$-dimensional quantum link models present in literature is discussed. Finally, the extension to three-dimensional lattices is presented, and its subtleties are pointed out.
