Finite 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.
متن کاملInteracting finite-size magnons
We explicitly construct a large class of finite-volume two-magnon string solutions moving on R × S. In particular, by making use of the relationship between the O(3) sigma model and sine-Gordon theory we are able to find solutions corresponding to the periodic analogues of magnon scattering and breather-like solutions. After semi-classically quantizing these solutions we invert the implicit exp...
متن کاملGiant magnons and spiky strings on the conifold
We find explicit solutions for giant magnons and spiky strings on the squashed three dimensional sphere. For a special value of the squashing parameter the solutions describe strings moving in a sector of the conifold, while for another value of the squashing parameter we recover the known results on the round three dimensional sphere. A new feature is that the energy and the momenta enter in t...
متن کاملFinite size giant magnons in the SU ( 2 ) × SU ( 2 ) sector of AdS 4 ×
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)...
