Giant Magnons on CP3 by Dressing Method
Abstract
We consider classical string spectrum of R x CP3, and construct a family of solutions with residual SU(2) symmetry by the dressing method on SU(4)/U(3) sigma model. All of them obey the square-root type dispersion relation, as is expected from the su(2|2) symmetry. A single dyonic giant magnon is not found in this approach.
