论文摘要
最近的原子物理学实验和数值工作报告了在具有阻滞相互作用的模型中拓扑量子自旋液体出现的互补特征。但是，稳定这种相的特定机制尚不清楚。在这里，我们介绍了关于kagome晶格的Ising-higgs晶格理论与Ruby Lattices上的模型之间的确切关系。这种关系通过将后者直接与可溶剂表理论的脱合阶段联系起来，阐明了先前观察到的拓扑自旋液体的起源。通过精确的对角线化和无偏的量子蒙特卡洛模拟，我们表明，缩合的相位在参数空间的宽区域中延伸。这些状态的特征是较大的基态重叠，并具有共鸣键波函数。这些封锁的模型既包括创造/歼灭和跳跃动力学，并且可以通过rydberg缝制的原子实现实验，从而为旋转液态态的工程和表征提供了新颖且可控制的平台。
Recent atomic physics experiments and numerical works have reported complementary signatures of the emergence of a topological quantum spin liquid in models with blockade interactions. However, the specific mechanism stabilizing such a phase remains unclear. Here, we introduce an exact relation between an Ising-Higgs lattice gauge theory on the kagome lattice and blockaded models on Ruby lattices. This relation elucidates the origin of previously observed topological spin liquids by directly linking the latter to a deconfined phase of a solvable gauge theory. By means of exact diagonalization and unbiased quantum Monte Carlo simulations, we show that the deconfined phases extend in a broad region of the parameter space; these states are characterized by a large ground state overlap with resonating valence bond wavefunctions. These blockaded models include both creation/annihilation and hopping dynamics, and can be experimentally realized with Rydberg-dressed atoms, offering novel and controllable platforms for the engineering and characterisation of spin liquid states.
