里德伯链提供了一个有吸引力的平台,探测共形场理论(CFTs),捕捉在无数的物理设置的普遍行为。专注于里德伯链在伊辛过渡分离电荷密度波和无序相,我们建立了一个详细的微观和低能量物理出现在临界点之间的联系。我们首先构建晶格化身的基本伊辛CFTincluding手征费米子,一个不平凡的任务,给出了里德伯链哈密顿不承认一个确切的费米子。有了这个字典在手,我们计算微观里德伯算子的相关性,特别注意有限的,开放的链的直接实验相关性。我们进一步发展了一种方法来量化第二近邻里德伯相互作用如何调整的符号和强度的四费米子耦合在伊辛CFT。最后,我们确定如何伊辛领域的演变时,四费米子耦合驱动伊辛三临界不稳定。我们的研究结果铺平了道路伊辛临界Rydberg阵列的一个彻底的实验表征,并可以告知新的高维相耦合的关键链的基础上的设计。
Rydberg chains provide an appealing platform for probing conformal field theories (CFTs) that capture universal behavior in a myriad of physical settings. Focusing on a Rydberg chain at the Ising transition separating charge density wave and disordered phases, we establish a detailed link between microscopics and low-energy physics emerging at criticality. We first construct lattice incarnations of primary fields in the underlying Ising CFTincluding chiral fermions, a nontrivial task given that the Rydberg chain Hamiltonian does not admit an exact fermionization. With this dictionary in hand, we compute correlations of microscopic Rydberg operators, paying special attention to finite, open chains of immediate experimental relevance. We further develop a method to quantify how second-neighbor Rydberg interactions tune the sign and strength of four-fermion couplings in the Ising CFT. Finally, we determine how the Ising fields evolve when four-fermion couplings drive an instability to Ising tricriticality. Our results pave the way to a thorough experimental characterization of Ising criticality in Rydberg arrays, and can inform the design of novel higher-dimensional phases based on coupled critical chains.
