Zero Modes for the Boundary Giant Magnons
We study the fermion zero-mode dynamics for open strings ending on the giant graviton branes. For the open string ending on the Z = 0 brane, the quantization of the fermion zero-modes of boundary giant magnons reproduces the 256 states of the boundary degrees with the precise realization of the SU(2|2)×SU(2|2) symmetry algebra. Also for the open string ending on the Y = 0 brane, we reproduce th...
متن کاملDyonic Giant Magnons
We study the classical spectrum of string theory on AdS5 × S in the HofmanMaldacena limit. We find a family of classical solutions corresponding to Giant Magnons with two independent angular momenta on S. These solutions are related via Pohlmeyer’s reduction procedure to the charged solitons of the Complex sine-Gordon equation. The corresponding string states are dual to BPS boundstates of many...
متن کاملMultispin Giant Magnons
We investigate giant magnons from classical rotating strings in two different backgrounds. First we generalize the solution of Hofman and Maldacena and investigate magnon excitations of a spin chain which are dual to a string on R× S with three nonvanishing angular momenta. We find a dispersion relation similar to that of Hofman and Maldacena and to the one found by Dorey for the two spin case ...
متن کاملQuantum Giant Magnons
The giant magnons are classical solitons of the O(N) sigma-model, which play an important role in the AdS/CFT correspondence. We study quantum giant magnons first at large N and then exactly using Bethe Ansatz, where giant magnons can be interpreted as holes in the Fermi sea. We also identify a solvable limit of Bethe Ansatz in which it describes a weakly-interacting Bose gas at zero temperatur...
متن کاملGiant Hedge-Hogs: Spikes on Giant Gravitons
We consider giant gravitons on the maximally supersymmetric plane-wave background of type IIB string theory. Fixing the light-cone gauge, we deduce the low energy effective light-cone Hamiltonian of the three-sphere giant graviton. At first order, this is a U(1) gauge theory on R × S. We place sources in this effective gauge theory. Although nonvanishing net electric charge configurations are d...
