论文摘要
我们提出了与可编程相互作用的Rydberg Atom阵列中介体和重型准粒子激发的实现。最近的实验表明，此类系统具有$ \ Mathbb {Z} _3 $订购的结晶相，其低能量准粒子是结晶顺序的缺陷。通过工程设计$ \ Mathbb {Z} _3 $ - 在Rydberg-Blockaded Hamiltonian之上，我们表明，不同类型的缺陷经历了限制，因此形成了Mesonic或Baryonic Quasiparticle刺激。我们通过研究与Rydberg Hamiltonian相关的量子性手性时钟模型来说明这些准粒子的形成。然后，我们提出了一个涉及不平衡动力学的实验协议，以直接探测受刺激的频谱。我们表明，限制的准粒子频谱可以限制该系统中量子信息扩散。该建议很容易适用于当前的Rydberg实验，并且该方法可以轻松地将其推广到具有$ \ Mathbb {Z} _Q $ order of $ q> 3 $的$ \ Mathbb {z} _Q $ order的阶段中更复杂的密闭激发（例如“ Tetraquarks”，``pentaquarks''）。
We propose a realization of mesonic and baryonic quasiparticle excitations in Rydberg atom arrays with programmable interactions. Recent experiments have shown that such systems possess a $\mathbb{Z}_3$-ordered crystalline phase whose low-energy quasiparticles are defects in the crystalline order. By engineering a $\mathbb{Z}_3$-translational-symmetry breaking field on top of the Rydberg-blockaded Hamiltonian, we show that different types of defects experience confinement, and as a consequence form mesonic or baryonic quasiparticle excitations. We illustrate the formation of these quasiparticles by studying a quantum chiral clock model related to the Rydberg Hamiltonian. We then propose an experimental protocol involving out-of-equilibrium dynamics to directly probe the spectrum of the confined excitations. We show that the confined quasiparticle spectrum can limit quantum information spreading in this system. This proposal is readily applicable to current Rydberg experiments, and the method can be easily generalized to more complex confined excitations (e.g. `tetraquarks', `pentaquarks') in phases with $\mathbb{Z}_q$ order for $q>3$.
