J. F. Gomes, L. H. Ymai, A. H. Zimerman

摘要:

在拉格朗日形式下,讨论了跳跃缺陷存在时可积场论的边界函数结构。明确的例子玻色子和费米子理论被认为是。特别地,构造了N=1和N=2的超sinh-Gordon模型的边界函数,并证明了其孤子解的Backlund变换。作为一个新的和有趣的例子,一个解决方案与传入玻色子和传出费米子的N=1的情况。所得的可积模型在超对称变换下是不变的。

英文摘要:

The structure of integrable field theories in the presence of jump defects is discussed in terms of boundary functions under the Lagrangian formalism. Explicit examples of bosonic and fermionic theories are considered. In particular, the boundary functions for the N=1 and N=2 super sinh-Gordon models are constructed and shown to generate the Backlund transformations for its soliton solutions. As a new and interesting example, a solution with an incoming boson and an outgoing fermion for the N=1 case is presented. The resulting integrable models are shown to be invariant under supersymmetric transformation.
