Neumann-Rosochatius integrable system for strings on AdS4 x CP3
Abstract
We use the reduction of the string dynamics on AdS4 x CP3 to the Neumann-Rosochatius integrable system. All constraints can be expressed simply in terms of a few parameters. We analyze the giant magnon and single spike solutions on Rt x CP3 with two angular momenta in detail and find the energy-charge relations. The finite-size effects of the giant magnon and single spike solutions are analyzed.
