标题： Meson spectroscopy of exotic symmetries of Ising criticality in Rydberg atom arrays

摘要： 伊辛模型作为探索量子临界系统中涌现对称性的典型平台。 一维伊辛链的临界点由共形伊辛场理论描述，在存在磁扰动的情况下仍保持可积性，导致与例外李代数$E_8$相关的大量粒子。 在梯子结构中耦合两条伊辛链会导致更丰富的$\mathcal{D}^{(1)}_8$对称性。 相关粒子激发的实验特征在钴铌$_2$氧$_6$自旋链材料的散射研究中已被认为被观察到。 在这里，我们利用其可调几何结构在里德伯原子量子处理单元中探测这些涌现对称性，实现了链和梯子结构。 我们在各自的临界点识别出与$E_8$和$\mathcal{D}^{(1)}_8$对称性一致的质量谱。 我们的结果展示了里德伯平台在研究量子多体系统中对称性涌现方面的强大能力，并提供了对约束、几何和临界性相互作用的直接观察窗口。 显示英文摘要

摘要： The Ising model serves as a canonical platform for exploring emergent symmetry in quantum critical systems. The critical point of the 1D Ising chain is described by a conformal Ising field theory, which remains integrable in the presence of a magnetic perturbation leading to massive particles associated with the exceptional Lie algebra $E_8$. Coupling two Ising chains in a ladder leads to an even richer $\mathcal{D}^{(1)}_8$ symmetry. Experimental signatures of the associated particle excitations have arguably been observed in scattering studies of the spin chain material CoNb$_2$O$_6$. Here, we probe these emergent symmetries in a Rydberg atom quantum processing unit, leveraging its tunable geometry to realize both chain and ladder configurations. We identify mass spectra consistent with $E_8$ and $\mathcal{D}^{(1)}_8$ symmetries at the respective critical points. Our results demonstrate the power of Rydberg platforms for investigating symmetry emergence in quantum many-body systems and provide a direct window into the interplay of confinement, geometry and criticality.
