摘要：

We consider the sine-Gordon model on a half-line, with an additional potential term of the form -M cos[1/2 beta(phi - phi(0))] at the boundary. We compute the classical time delay for general values of M, beta and phi(0) using tau-function methods and show that in the classical limit the method of images still works, despite the non-linearity of the problem. We also perform a semi-classical analysis, and find agreement with the exact quantum S-matrix conjectured by Ghoshal and Zamolodchikov.
