Sine-Gordon理论中呼吸子边界形状因子

Breather boundary form factors in sine-Gordon theory

M. Lencses, G. Takacs

摘要:

用边界sine-Gordon理论中边界截断共形空间方法的数值结果检验了sinh-Gordon模型中边界指数算子的一组精确形状因子。我们发现,数值数据强烈支持的有效性的形状因子本身,但是,我们也报告了一个差异的情况下,对角矩阵元素,这仍然是悬而未决的时间。

英文摘要:

A previously conjectured set of exact form factors of boundary exponential operators in the sinh-Gordon model is tested against numerical results from boundary truncated conformal space approach in boundary sine-Gordon theory, related by analytic continuation to sinh-Gordon model. We find that the numerical data strongly support the validity of the form factors themselves; however, we also report a discrepancy in the case of diagonal matrix elements, which remains unresolved for the time being.
