摘要:

当中性原子的电子被激发到弱束缚的 Rydberg 态时,它们会变得具有强相互作用。我们研究了在二维原子阵列中涌现的强关联量子物质相,其中使用了三个 Rydberg 能级来编码一个有效的 spin-1 自由度。此类 spin-1 Rydberg 原子间的偶极交换自然地产生了两种不同的模型:(i) 一种两组分硬核玻色子模型,以及 (ii) 在调节至接近 Förster 共振时,一种偶极 spin-1 XY 模型。通过广泛的大规模无限密度矩阵重正化群计算,我们提供了一个广泛的路线图,预测了这些模型在多种晶格几何结构(包括 square、triangular、kagome 和 ruby)上涌现的量子相。我们识别出了丰富的关联态,包括晶格超固态和单纯形相,所有这些状态都可以在近期的实验中自然实现。

英文摘要:

Neutral atoms become strongly interacting when their electrons are excited to loosely bound Rydberg states. We investigate the strongly correlated quantum phases of matter that emerge in two-dimensional atom arrays where three Rydberg levels are used to encode an effective spin-1 degree of freedom. Dipolar exchange between such spin-1 Rydberg atoms naturally yields two distinct models: (i) a two-species hardcore boson model, and (ii) upon tuning near a Förster resonance, a dipolar spin-1 XY model. Through extensive, large-scale infinite density matrix renormalization group calculations, we provide a broad roadmap predicting the quantum phases that emerge from these models on a variety of lattice geometries: square, triangular, kagome, and ruby. We identify a wealth of correlated states, including lattice supersolids and simplex phases, all of which can be naturally realized in near-term experiments.
