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...
متن کاملQuantum fluctuations of rotating strings in AdS 5 × S 5
We discuss quantum fluctuations of a class of rotating strings in AdS5×S. In particular, we develop a systematic method to compute the one-loop sigma-model effective actions in closed forms as expansions for large spins. As examples, we explicitly evaluate the leading terms for the constant radii strings in the SO(6) sector with two equal spins, the SU(2) sector, and the SL(2) sector. We also o...
متن کاملOn the Scattering Phase for AdS 5 × S 5 Strings
We propose an exact phase factor of the worldsheet S-matrix for strings on AdS5 × S. It agrees with results of perturbative string theory and apparently solves Janik’s crossing relation.
متن کاملA Crossing – Symmetric Phase for AdS 5 × S 5 Strings
We propose an all-order perturbative expression for the dressing phase of the AdS5 × S string S-matrix at strong coupling. Moreover, we are able to sum up large parts of this expression. This allows us to start the investigation of the analytic structure of the phase at finite coupling revealing a few surprising features. The phase obeys all known constraints including the crossing relation and...
متن کاملNahm ’ s equations , N = 1 ∗ domain walls , and D - strings in AdS 5 × S 5
We consider the following two problems: classical domain walls in the N = 1∗ mass deformation of the maximally supersymmetric Yang Mills theory, and D-strings as external magnetic sources in the context of the AdS/CFT correspondence. We show that they are both described by Nahm’s equations with unconventional boundary conditions, and analyze the relevant moduli space of solutions. We argue that...
