我们推导出一个模拟的主方程，最近获得的XXZ链的相关函数，为广泛的一类量子可积系统所描述的R-矩阵的六顶点模型，包括特别是连续模型。这个广义主方程使我们能够获得这些模型的相关函数的多个积分表示。我们应用这种方法导出了量子非线性薛定谔模型的密度-密度关联函数。
We derive an analogue of the master equation, obtained recently for correlation functions of the XXZ chain, for a wide class of quantum integrable systems described by the R-matrix of the six-vertex model, including in particular continuum models. This generalized master equation allows us to obtain multiple integral representations for the correlation functions of these models. We apply this method to derive the density–density correlation functions of the quantum non-linear Schrödinger model.
