The image sector in the string dual of image superconformal Chern–Simons theory Original Research Article

We examine the string dual of the recently constructed image superconformal Chern–Simons theory of Aharony, Bergman, Jafferis and Maldacena (ABJM theory). We focus in particular on the image sector. We find a sigma-model limit in which the resulting sigma-model is two Landau–Lifshitz models added together. We consider a Penrose limit for which we can approach the image sector. Finally, we find a new Giant Magnon solution in the image sector corresponding to one magnon in each image. We put these results together to find the full magnon dispersion relation and we compare this to recently found results for ABJM theory at weak coupling.
