论经典与量子可积理论之间对应关系的起源

On the origin of the correspondence between classical and quantum integrable theories

Davide Fioravanti, Marco Rossi

AI总结:

本文从定义量子可积理论的泛函关系出发,经线性积分方程与 Marchenko 型方程推导经典 Lax 对,阐明 ODE/IM 对应及经典—量子可积理论联系的起源。

摘要:

如果我们从某些泛函关系出发,将其作为量子可积理论的定义,那么就能从中推导出一个线性积分方程。通过引入动力学变量,该方程可被扩展为具有 Marchenko 方程形式的方程。随后,我们从后者推导出一个经典(微分)Lax 对。我们以 ODE/IM(常微分方程/可积模型)对应的有质量版本为例来说明该方法:它从具有多个模/质量的 Quantum sine-Gordon(sG)理论通向经典 sinh-Gordon(shG)方程,从而在一个特殊情形中描述某些超对称规范理论以及 $AdS_3$ 强耦合散射振幅/Wilson 圈。不过,我们的表述方式揭示了该方法应用上的普遍性。事实上,我们还就其如何适用于自旋链给出了若干提示。

英文摘要:

If we start from certain functional relations as definition of a quantum integrable theory, then we can derive from them a linear integral equation. It can be extended, by introducing dynamical variables, to become an equation with the form of Marchenko's. Then, we derive from the latter a classical (differential) Lax pair. We exemplify our method by focusing on the massive version of the ODE/IM (Ordinary Differential Equations/Integrable Models) correspondence from Quantum sine-Gordon (sG) with many moduli/masses to the classical sinh-Gordon (shG) equation, so describing, in a particular case, some super-symmetric gauge theories and the $AdS_3$ strong coupling scattering amplitudes/Wilson loops. Yet, we present it in a way which reveals its generality of application. In fact, we give some hints on how it works for spin chains.
