无界多磁振子与Spike

Unbounded Multi-Magnon and Spike

Bum-Hoon Lee, Chanyong Park

摘要:

我们将R × S ^2中的单磁振子解推广到无界M磁振子,并在弦西格玛模型中找到了相应的孤子弦组态。这种配置产生了预期的色散关系,从自旋链模型在大的t Hooft耦合极限。考虑R × S^2 × S^2上的(M,M)多磁振子或尖峰作为AdS(5)XS ^5或AdS(4)XCP ^3的子空间,研究了(M,M)多磁振子或尖峰的色散关系和有限尺寸效应。

英文摘要:

We generalize the one magnon solution in R X S^2 to unbounded M magnon and find the corresponding solitonic string configuration in the string sigma model. This configuration gives rise to the expected dispersion relation obtained from the spin chain model in the large 't Hooft coupling limit. After considering (M,M) multi-magnon or spike on R X S^2 X S^2 as a subspace of AdS(5)XS^5 or AdS(4)XCP^3, we investigate the dispersion relation and the finite size effect for (M,M) multi-magnon or spike.
