Defining the AdS/CFT Y-system and Solving it Using a Finite Set of Equations
Speaker(s): Dmytro Volin
Abstract: I will show how to solve the AdS/CFT Y-system in terms of a finite set of nonlinear integral equations (FiNLIE). To uniquely define the solution we impose the set of constraints on the Y- and T-functions which can be summarized as: symmetry (PSU(2,2|4) + Z_4) + analyticity + large volume asymptotics... read more

First-principles Derivation of the AdS/CFT Y- and T-systems
Speaker(s): Raphael Benichou
Abstract: I will present a first-principles derivation of the AdS5/CFT4 T-system up to first non-trivial order in the large 't Hooft coupling expansion. The proof relies on the computation of quantum effects in the fusion of some special line operators, namely the transfer matrices. This computation is done i... read more

A Relativistic Relative of GS Superstrings on AdS5 x S5
Speaker(s): J. Luis Miramontes
Abstract: The motion of superstrings on symmetric space target spaces is classically equivalent, via the Pohlmeyer reduction, to a family of 2-d relativistic integrable field theories known as semisymmetric space sine-Gordon (SSSSG) theories. In this talk I will review recent progress in constructing the rela... read more

N=1 SQCD and the Transverse Field Ising Model
Abstract: We study the dimensions of non-chiral operators in the Veneziano limit of N=1 supersymmetric QCD in the conformal window. We show that when acting on gauge-invariant operators built out of scalars, the 1-loop dilatation operator is equivalent to the spin chain Hamiltonian of the 1D Ising model in a ... read more
