AdS4 x CP3中的巨磁振子:嵌入、电荷和哈密顿量

Giant Magnons in AdS4 x CP3: Embeddings, Charges and a Hamiltonian

Michael C. Abbott, Inês Aniceto

摘要:

本文研究了CP 3中的巨磁振子,在所有已知的情况下,这些巨磁振子都是从S5放入CP 3的二维和三维子空间,即CP 1,RP 2和RP 3中的旧解。我们澄清了一些关于这些子空间,和其他潜在的有趣的三维和四维子空间。在确定了E-(J1-J 4)/2是相应的“真空”点粒子解的小涨落的哈密顿量后,我们用它计算了各不等价巨磁振子的色散关系。我们评论的嵌入有限J的解决方案,并使用这些比较字符串解决方案的代数曲线中的巨磁振子。

英文摘要:

This paper studies giant magnons in CP3, which in all known cases are old solutions from S5 placed into two- and three-dimensional subspaces of CP3, namely CP1, RP2 and RP3. We clarify some points about these subspaces, and other potentially interesting three- and four-dimensional subspaces. After confirming that E-(J1-J4)/2 is a Hamiltonian for small fluctuations of the relevant 'vacuum' point particle solution, we use it to calculate the dispersion relation of each of the inequivalent giant magnons. We comment on the embedding of finite-J solutions, and use these to compare string solutions to giant magnons in the algebraic curve.
