Dyonic Giant Magnons in CP3 : Strings and Curves at Finite J

• This paper studies giant magnons in AdS4×CP3 using both the string sigma model and the algebraic curve. We complete the dictionary of solutions by finding the dyonic generalization of the CP1string solution, which matches the “small” giant magnon in the algebraic curve, and by pointing out that the solution recently constructed by the dressing method is the “big” giant magnon. We then use the curve to compute finite-J corrections to all cases, which for the nondyonic cases always match the Arutyunov-Frolov-Zamaklar result. For the dyonic RP3 magnon we recover the S5answer, but for the small and big giant magnons we obtain new corrections.
