研究构建酉矩阵模型与量子自旋链真空关联函数的对应关系,核心方法是将对称函数提升为算符,主要贡献是在酉矩阵积分、量子可积系统和对称函数理论间搭建统一代数桥梁,并通过多种模型说明。

摘要:

我们构建了一类广泛的酉矩阵模型与量子自旋链希尔伯特空间中真空关联函数之间的对应关系。关键步骤是以保留相关环结构的方式将对称函数提升为作用于\(N\)磁振子扇区的算符。对于任何其被积函数允许在对称函数中进行因式分解展开的酉矩阵模型,酉群积分的舒尔正交性随后转化为量子化舒尔态的内积。我们通过格罗斯 - 维滕 - 瓦迪亚模型、具有经典规范群的\(\mathcal{N}=4\)超杨 - 米尔斯理论的超共形指标以及托达\(\tau\)函数来说明该构建。所得的算符表述在酉矩阵积分、量子可积系统和对称函数理论之间提供了一个统一的代数桥梁。

英文摘要:

We construct a correspondence between a broad class of unitary matrix models and vacuum correlation functions in quantum spin-chain Hilbert spaces. The key step is to lift symmetric functions to operators acting on the $N$-magnon sector in a way that preserves the relevant ring structure. For any unitary matrix model whose integrand admits a factorized expansion in symmetric functions, the Schur orthogonality of the unitary group integral is then translated into the inner product of quantized Schur states. We illustrate the construction for the Gross--Witten--Wadia model, superconformal indices of $\mathcal{N}=4$ super Yang--Mills theory with classical gauge groups, and Toda tau functions. The resulting operator formulation provides a unified algebraic bridge between unitary matrix integrals, quantum integrable systems and symmetric function theory.
