Improved Stability for Pulsating Multi-Spin String Solitons

We derive and analyse, analytically and numerically, the equations for perturbations around the pulsating two-spin string soliton in AdS 5 × S 5. We show that the pulsation in S 5 indeed improves the stability properties of the two-spin string soliton in AdS 5 , in the sense that the more pulsation we have, the higher spin we can allow and still have stability.

N ov 2 00 4 Pulsating strings in warped AdS 6 × S 4 geometry

In this paper we consider pulsating strings in warped AdS 6 × S 4 background, which is a vacuum solution of massive type IIA super-string. The case of rotating strings in this background was considered in hep-th/0402202 and it was found that the results significantly differs from those considered in AdS 5 ×S 5. Motivated by this results we study pulsating strings in the warped spherical part of...

We construct a family of closed string solutions with kinks in a subspace of AdS5 × S and study their properties. In certain limits these solutions become folded pulsating strings, although in general they are made of multiple pulsating rectangles. One unusual feature of these solutions is that their monodromy matrices are trivial, leading to vanishing quasi-momenta. Exact Bäcklund transformati...

5 Spinning strings and integrable spin chains in the AdS / CFT correspondence

In this introductory review we discuss recent dynamical tests of the AdS 5 × S 5 string/N = 4 super Yang-Mills duality. After a brief introduction to AdS/CFT we argue that semiclassical string energies yield information on the quantum spectrum of the string in the limit of large angular momenta. The energies of the folded and circular spinning string solutions rotating on a S 3 within the S 5 a...
