一个新的初等CP ^n双子磁振子
A New and Elementary CP^n Dyonic Magnon
摘要:
我们证明了Dressing变换方法产生了一种新型的双音CP^n磁振子,在这种磁振子中,所有其他已知的解要么是复合的,要么是作为特殊极限出现的。特别地,这包括通过CP^n的RP ^3子空间嵌入多雷的双子磁振子。我们还展示了如何在S^n西格玛模型中通过dressing方法直接产生Dorey双子磁振子,而不需要求助于与SU(2)原理手征模型的同构(当n=3时)。新的双子要么是带电双子,要么是与CP^n相关的复空间sine-Gordon理论的拓扑扭结,在这个意义上,它是复sine-Gordon理论孤子的直接推广。
英文摘要:
We show that the dressing transformation method produces a new type of dyonic CP^n magnon in terms of which all the other known solutions are either composites or arise as special limits. In particular, this includes the embedding of Dorey's dyonic magnon via an RP^3 subspace of CP^n. We also show how to generate Dorey's dyonic magnon directly in the S^n sigma model via the dressing method without resorting to the isomorphism with the SU(2) principle chiral model when n=3. The new dyon is shown to be either a charged dyon or topological kink of the related symmetric-space sine-Gordon theories associated to CP^n and in this sense is a direct generalization of the soliton of the complex sine-Gordon theory.
