AI中文摘要:
我们引入了一种图不变量,该不变量通过从局部图邻域导出的哈密顿量的泡利分解获得。给定一个以根节点为中心的h跳邻域,我们构造一个局部邻接算子,将其嵌入到公共希尔伯特空间维度中,并将其泡利支撑集定义为具有非零系数的泡利字符串的集合。对于周期图,我们证明了在格相容图等价下的不变性,并在根分离假设下建立了逆命题。该框架自然扩展到由相关泡利支撑生成的李闭包、交换子和嘉当型结构。我们进一步讨论了具有有限局部复杂性的非周期图的扩展,并与准晶体的切割投影模型(尤其是彭罗斯镶嵌)建立了联系。从量子信息的角度来看,所得不变量提供了基于图的哈密顿量的算子理论描述,并为通过泡利支撑数据比较基于图的量子系统提供了一种新机制。
英文摘要:
We introduce a graph invariant obtained from Pauli decompositions of Hamiltonians derived from local graph neighborhoods. Given a rooted h-hop neighborhood, we construct a local adjacency operator, embed it into a common Hilbert space dimension, and define its Pauli-support set as the collection of Pauli strings appearing with nonzero coefficients. For periodic graphs, we prove invariance under lattice-compatible graph equivalence and establish converse results under root-separation hypothesis. The framework naturally extends to Lie closures, commutants, and Cartan-type structures generated by the associated Pauli supports. We further discuss extensions to aperiodic graphs with finite local complexity and make connections to cut-and-project models of quasicrystals and notably, Penrose tilings. From a quantum information perspective, the resulting invariants provide a operator-theoretic description of graph-based Hamiltonians and offer a new mechanism for comparing graph-based quantum systems through Pauli-support data.
