Giant Magnons in AdS 4 × CP 3 : Embeddings , Charges and a Hamiltonian

چکیده

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 particle solution, we use it to calculate the dispersion relation of each of the inequivalent giant magnons. We comment on the embedding of finite-J solutions, and use these to compare string solutions to giant magnons in the algebraic curve.

Finite size giant magnons in the SU ( 2 ) × SU ( 2 ) sector of AdS 4 × CP 3 Tomasz Lukowski 1 and Olof

We use the algebraic curve and Lüscher’s μ-term to calculate the leading order finite size corrections to the dispersion relation of giant magnons in the SU(2)× SU(2) sector of AdS4 ×CP3. We consider a single magnon as well as one magnon in each SU(2). In addition the algebraic curve computation is generalized to give the leading order correction for an arbitrary multi-magnon state in the SU(2)...

Near Flat Space limit of strings on AdS 4 × CP 3

The non-linear nature of string theory on non-trivial backgrounds related to the AdS/CFT correspondence suggests to look for simplifications. Two such simplifications proved to be useful in studying string theory. These are the pp-wave limit which describes point-like strings and the so called “near flat space” limit which connects two different sectors of string theory – pp-waves and “giant ma...

Giant 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 ...
