The SU(2) Long Range Bethe Ansatz and Continuous Integrable Systems

We explore the relationship between the SU(2) sector of a general integrable field theory and the all-loop guess for the anomalous dimensions of SU(2) operators in N=4 super Yang-Mills theory. We…

Bethe Ansatz solutions for highest states in Script N = 4 SYM and AdS/CFT duality

We consider the operators with highest anomalous dimension Δ in the compact rank-one sectors (1|1) and (2) of = 4 super Yang-Mills. We study the flow of Δ from weak to strong 't Hooft coupling λ by…

Analytic Bethe Ansatz and Baxter equations for long-range psl(2|2) spin chain

The Analytic Bethe Ansatz for a Chain with Centrally Extended su ( 2 | 2 ) Symmetry

We investigate the integrable structure of spin chain models with centrally extended su(2|2) and psu(2, 2|4) symmetry. These chains have their origin in the planar AdS/CFT correspondence, but they…

Two-loop test of the N = 6 Chern-Simons theory S-matrix

Starting from the integrable two-loop spin-chain Hamiltonian describing the anomalous dimensions of scalar operators in the planar = 6 superconformal Chern-Simons theory of ABJM, we perform a direct…

: We consider the operators with highest anomalous dimension ∆ in the compact rank-one sectors su (1 | 1) and su (2) of N = 4 super Yang-Mills. We study the flow of ∆ from weak to strong ’t Hooft…

Integrable spin chain in superconformal Chern-Simons theory

N = 6 superconformal Chern-Simons theory was proposed as gauge theory dual to Type IIA string theory on AdS4 ⊗ CP 3 . We study integrability of the theory from conformal dimension spectrum of single…

Finite size corrections and integrability of = 2 SYM and DLCQ strings on a pp-wave

: We compute the planar flnite size corrections to the spectrum of the dilatation operator acting on two-impurity states of a certain limit of conformal N = 2 quiver gauge fleld theory which is a Z M…

Reconstructing 1/2 BPS space-time metrics from matrix models and spin chains

Using the anti-de Sitter/conformal field theories (AdS/CFT) correspondence, we address the question of how to measure complicated space-time metrics using gauge theory probes. In particular, we…

Complete 1-loop test of AdS/CFT

We analyze nested Bethe ansatz (NBA) and the corresponding finite size corrections. We find an integral equation which describes these corrections in a closed form. As an application we considered…

A Novel Long Range Spin Chain and Planar N=4 Super Yang-Mills

We probe the long-range spin chain approach to planar N = 4 gauge theory at high loop order. A recently employed hyperbolic spin chain invented by Inozemtsev is suitable for the su(2) subsector of…

Planar N=4 Gauge Theory and the Inozemtsev Long Range Spin Chain

We investigate whether the (planar, two complex scalar) dilatation operator of N = 4 gauge theory can be, perturbatively and, perhaps, non-perturbatively, described by an integrable long range spin…

The su ( 2 | 3 ) Dynamic Spin Chain

The complete one-loop, planar dilatation operator of the N = 4 supercon-formal gauge theory was recently derived and shown to be integrable. Here, we present further compelling evidence for a…

We propose Bethe equations for the diagonalization of the Hamiltonian of quantum strings on AdS5 ×S 5 at large string tension and restricted to certain large charge states from a closed su(2)…

The Bethe-ansatz for N = 4 super Yang-Mills

We derive the one loop mixing matrix for anomalous dimensions in N=4 Super Yang-Mills. We show that this matrix can be identified with the Hamiltonian of an integrable SO(6) spin chain with vector…

The factorized S-matrix of CFT/AdS

We argue that the recently discovered integrability in the large-N CFT/AdS system is equivalent to diffractionless scattering of the corresponding hidden elementary excitations. This suggests that,…
