Sklyanin SOV关于可积量子模型循环表示的Bethe证明的完备性

Completeness of Bethe Ansatz by Sklyanin SOV for Cyclic Representations of Integrable Quantum Models

G. Niccoli

摘要:

在文献[1]中引入了一个可积量子模型,并证明了它的一类循环表示可以定义Sine-Gordon模型的格正则化。本文在Sklyanin的变量分离(SOV)框架下,通过扩展[2]中引入的谱结构,分析了这个可积量子模型的一般循环表示。我们证明了,如在[1]中一样,对于一般表示,转移矩阵谱(本征值和本征态)完全由相关泛函Baxter方程的多项式解来表征。此外,我们证明了这里开发的方法有两个基本的内置功能:i)的完整性的传输矩阵本征态的一组构造从相关的Bethe anesthesia方程的解决方案,ii)的存在性和Baxter Q算子的完整表征。

英文摘要:

In [1] an integrable quantum model was introduced and a class of its cyclic representations was proven to define lattice regularizations of the Sine-Gordon model. Here, we analyze general cyclic representations of this integrable quantum model by extending the spectrum construction introduced in [2] in the framework of the Separation of Variables (SOV) of Sklyanin. We show that as in [1] also for general representations, the transfer matrix spectrum (eigenvalues and eigenstates) is completely characterized in terms of polynomial solutions of an associated functional Baxter equation. Moreover, we prove that the method here developed has two fundamental built-in features: i) the completeness of the set of the transfer matrix eigenstates constructed from the solutions of the associated Bethe ansatz equations, ii) the existence and complete characterization of the Baxter Q-operator.
