Aspects of the Generalized Unitarity Method
Speaker(s): Radu Roiban
Abstract: The generalized unitarity method reconstructs loop-level scattering amplitudes from tree-level scattering amplitudes. We review some of the steps of this method which are necessary for applications in any quantum field theory, discuss several points of view and emphasize some of the aspects that can... read more

Towards 3-Point Correlation Functions of Heavy Operators
Speaker(s): Romuald Janik
Abstract: In this talk I will report on the computation at strong coupling of the AdS contribution to the 3-point correlation function of operators corresponding to classical strings which rotate in the S5. This contribution is universal for all operators which have only SO(6) charges.

Quasiclassical 3pt Functions
Speaker(s): Nikolay Gromov
Abstract: We compute three-point functions of single trace operators in planar N = 4 SYM. We consider the limit where one of the operators is much smaller than the other two. We find a precise match between weak and strong coupling in the Frolov-Tseytlin classical limit for a very general class of classical ... read more

Aspects of Quantum Pohlmeyer Reduced Theory for AdS5 x S5 Superstring
Speaker(s): Arkady Tseytlin
Abstract: We will discuss recent progress in computing quantum corrections to S-matrix and partition function of Pohlmeyer reduction for AdS5 x S5 superstring theory.

Euclidean Wilson Loops and Riemann Theta Functions
Speaker(s): Martin Kruczenski
Abstract: For N=4 super Yang-Mills theory, in the large-N limit and at strong coupling, Wilson loops can be computed using the AdS/CFT correspondence. In the case of flat Euclidean loops the dual computation consists in finding minimal area surfaces in Euclidean AdS3 space. In such case very few solutions wer... read more

Fermionic Basis of Local Fields in the Sine-Gordon Model
Speaker(s): Michio Jimbo
Abstract: In this talk we give a survey of recent developments concerning the fermionic structure in the sine-Gordon model. For the lattice counterpart (6 vertex model), we introduce fermions acting on the space of (quasi) local operators. The main theorem is a determinant formula for the expectation values o... read more

On the Ratio of the Viscosity to Entropy Density for Quantum Gases in the Unitary Limit
Speaker(s): Andre LeClair
Abstract: In the so-called unitary limit of quantum gases, the scattering length diverges and the theory becomes scale invariant with dynamical exponent z=2. This point occurs precisely at the crossover between strongly coupled BEC and BCS. These systems are currently under intense experimental study using co... read more
