Johannes Branahl, Alexander Hock

AI总结:

本文通过引入两族关联函数并建立 Dyson-Schwinger 方程,证明了具有四次势的 LSZ 模型遵循拓扑递归,从而展示了其精确可解性,并为量子场论的可积性提供了新途径。

摘要:

我们证明了具有四次势的 Langmann-Szabo-Zarembo (LSZ) 模型,即作为复矩阵模型理解的非交换空间上量子场论的玩具模型,遵循 Chekhov、Eynard 和 Orantin 的拓扑递归。通过引入两族关联函数(其中一族对应于拓扑递归的亚纯微分 $ω_{g,n}$),我们得到了 Dyson-Schwinger 方程,这些方程最终导出了抽象环方程,这些环方程连同其极点结构,构成了拓扑递归的必要条件。这种展示 LSZ 模型精确可解性的策略,为某些量子场论中可积性的特殊性质确立了另一种途径。我们比较了 LSZ 模型(具有复场)和 Grosse-Wulkenhaar 模型(具有厄米场)的环方程差异,及其对控制这些模型的特定拓扑递归类型所产生的影响。

英文摘要:

We prove that the Langmann-Szabo-Zarembo (LSZ) model with quartic potential, a toy model for a quantum field theory on noncommutative spaces grasped as a complex matrix model, obeys topological recursion of Chekhov, Eynard and Orantin. By introducing two families of correlation functions, one corresponding to the meromorphic differentials $ω_{g,n}$ of topological recursion, we obtain Dyson-Schwinger equations that eventually lead to the abstract loop equations being, together with their pole structure, the necessary condition for topological recursion. This strategy to show the exact solvability of the LSZ model establishes another approach towards the exceptional property of integrability in some quantum field theories. We compare differences in the loop equations for the LSZ model (with complex fields) and the Grosse-Wulkenhaar model (with hermitian fieldss) and their consequences for the resulting particular type of topological recursion that governs the models.
