从Sklyanin SOV重构Baxter Q算子用于可积量子模型的循环表示

Reconstruction of Baxter Q-operator from Sklyanin SOV for cyclic representations of integrable quantum models

G. Niccoli

摘要:

在文献[1]中,Sine-Gordon模型的格点正则化的谱(本征值和本征态)已完全用具有Baxter方程某些性质的多项式解来刻画。循环表示的这个特征已经通过使用Sklyanin的变量分离(SOV)方法和Baxter Q-算子族的直接构造而导出。在这里,我们重建巴克斯特Q-算子和相同的表征的频谱只使用SOV方法。这种分析使我们能够推导出扩展到其他可积量子模型的这种谱表征的循环表示所需的主要功能。

英文摘要:

In [1], the spectrum (eigenvalues and eigenstates) of a lattice regularizations of the Sine-Gordon model has been completely characterized in terms of polynomial solutions with certain properties of the Baxter equation. This characterization for cyclic representations has been derived by the use of the Separation of Variables (SOV) method of Sklyanin and by the direct construction of the Baxter Q-operator family. Here, we reconstruct the Baxter Q-operator and the same characterization of the spectrum by only using the SOV method. This analysis allows us to deduce the main features required for the extension to cyclic representations of other integrable quantum models of this kind of spectrum characterization.
