CP ^3上的缀饰巨磁振子

Dressed Giant Magnons on CP^3

Chrysostomos Kalousios, Marcus Spradlin, Anastasia Volovich

摘要:

ABJM最近提供了一个AdS/CFT对偶的新例子,它将AdS_4 x CP ^3上的IIA弦论与N=6超共形陈-西蒙斯理论联系起来。到目前为止,已经有许多论文考虑了CP ^[3]背景下的特殊巨磁振子经典弦解,对应于对偶场论自旋链图中的激发。本文应用CP ^3 = SU(4)/S(U(3)x U(1))dressing方法构造描述巨磁振子各种组态的一般经典弦解。作为一个特殊的应用,我们给出了CP ^3上一个新的巨磁振子解。有趣的是,修饰后的溶液只带有一个SO(6)电荷,这与以前应用修饰方法时发现的双子磁振子相反。

英文摘要:

A new example of AdS/CFT duality relating IIA string theory on AdS_4 x CP^3 to N=6 superconformal Chern-Simons theory has recently been provided by ABJM. By now a number of papers have considered particular giant magnon classical string solutions in the CP^3 background, corresponding to excitations in the spin chain picture of the dual field theory. In this paper we apply the CP^3 = SU(4)/S(U(3) x U(1)) dressing method to the problem of constructing general classical string solutions describing various configurations of giant magnons. As a particular application we present a new giant magnon solution on CP^3. Interestingly the dressed solution carries only a single SO(6) charge, in contrast with the dyonic magnons found in previous applications of the dressing method.
