边界Liouville理论的算子方法

Operator Approach to Boundary Liouville Theory

Harald Dorn, George Jorjadze

摘要:

本文提出了一种新的方法,用于计算具有洛伦兹特征的带上的边界刘维尔理论的离散谱、反射振幅和关联函数。它们是基于顶点算子$V=e^{-ϕ}$的渐近算子的结构。首先测试的方法在莫尔斯潜在的粒子动力学,类似的结构出现。应用我们的方法边界刘维尔理论再现了已知的结果得到较早的自举方法,但可能会出现一定的扩展时,边界参数接近临界值。也就是说,在这种情况下,我们已经找到了多达四个不同的等距系列的离散光谱,并分别修改反射振幅。

英文摘要:

We propose new methods for calculation of the discrete spectrum, the reflection amplitude and the correlation functions of boundary Liouville theory on a strip with Lorentzian signature. They are based on the structure of the vertex operator $V=e^{-ϕ}$ in terms of the asymptotic operators. The methods first are tested for the particle dynamics in the Morse potential, where similar structures appear. Application of our methods to boundary Liouville theory reproduces the known results obtained earlier in the bootstrap approach, but there can arise a certain extension when the boundary parameters are near to critical values. Namely, in this case we have found up to four different equidistant series of discrete spectra, and the reflection amplitude is modified respectively.
