Sinh-Gordon边界TBA和边界Liouville反射振幅

Sinh-Gordon Boundary TBA and Boundary Liouville Reflection Amplitude

Z. Bajnok, Chaiho Rim, Al. Zamolodchikov

摘要:

利用边界热力学Bethe近似方程研究了定义在带上的sinh-Gordon模型的基态能量。它的紫外(小宽度的带)的行为进行了比较,从边界刘维尔反射振幅。结果在参数的允许范围内是完全一致的,并为这两种方法提供了令人信服的支持。我们还描述了当Liouville零模形成束缚态时,有效中心荷的紫外极限如何在参数范围内超过1。

英文摘要:

The ground state energy of the sinh-Gordon model defined on the strip is studied using the boundary thermodynamic Bethe ansatz equation. Its ultraviolet (small width of the strip) behavior is compared with the one obtained from the boundary Liouville reflection amplitude. The results are in perfect agreement in the allowable range of the parameters and provide convincing support for both approaches. We also describe how the ultraviolet limit of the effective central charge can exceed one in the parameter range when the Liouville zero mode forms a bound state.
