非线性薛定谔模型边界场算子的形式因子

Form factors of the operators at the boundary in quantum nonlinear Schrdinger model*

讨论了可积开边界条件下的非线性薛定谔模型,给出了其贝特本征态的内积和模长.在此基础上得到了边界场算子的形式因子.这些结果均被表达成由谱参量的函数所构成的行列式.

For the nonlinear Schroedinger model with an integrable open boundary, the scalar products of Bethe eigenstates and form factors of operators at the boundary are calculated. The results are represented as determinants of usual functions with parameters of the model.
