On String Integrability: A Journey through the Two-Dimensional Hidden Symmetries in the AdS/CFT Dualities

Figure 6

Near-flat-space limit. It interpolates between the plane wave regime and the giant magnon regime. The diagram shows the energy as a function of the momentum. In the plane wave limit the momentum p scales as ∼𝜆^−1/2, in the NFS region 𝑝∼𝜆^−1/4 and finally in the giant magnon regime p is a constant (an angle).
