Zero Modes for the Boundary Giant Magnons
نویسنده
چکیده
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 the unique vacuum state from the fermion zero-modes.

Quantum 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 magnons in the D1-D5 system
We study giant magnons in the the D1-D5 system from both the boundary CFT and as classical solutions of the string sigma model in AdS3 × S × T . Re-examining earlier studies of the symmetric product conformal field theory we argue that giant magnons in the symmetric product are BPS states in a centrally extended SU(1|1)×SU(1|1) superalgebra with two more additional central charges. The magnons ...
متن کاملA Perspective on Classical Strings from Complex Sine-Gordon Solitons
We study a family of classical string solutions with large spins on Rt×S subspace of AdS5×S background. These solutions are related to Complex sine-Gordon solitons via Pohlmeyer’s reduction. The equations of motion for the classical strings are cast into Lamé equations and Complex sine-Gordon equations. We solve them under periodic boundary conditions, and obtain analytic profiles for the close...
متن کاملGiant Magnons in AdS 4 × CP 3 : Embeddings , Charges and a Hamiltonian
This paper studies giant magnons in CP , which in all known cases are old solutions from S placed into twoand three-dimensional subspaces of CP , namely CP , RP 2 and RP . We clarify some points about these subspaces, and other potentially interesting threeand four-dimensional subspaces. After confirming that ∆ − (J1 − J4)/2 is a Hamiltonian for small fluctuations of the relevant ‘vacuum’ point...
متن کاملFinite size giant magnons and interactions
Magnon interactions give important contributions to the wrapping interactions of the N = 4 spin-chain. Similar effects are expected for the finite size corrections to the giant magnon energy in AdS5 × S. In this paper I review the finite gap description of giant magnons and the leading order calculation of the finite size corrections to the giant magnon dispersion relation for multi-magnon states.
