- TBA: Francesco Galvano (Torino): Wilson loops in N=2 SuperConformal Field theories (Note that this seminar will be in Seminar room 07a)
Abstract: The partition function of a four dimensional N=2 Super Yang-Mills theory can be mapped to a matrix model on a sphere using supersymmetric localization. We write it in a superconformal case, playing with the matter content in different representations of the gauge group. In this set-up we compute the vacuum expectation value a 1/2 BPS Maldacena-Wilson loop and we mention possible holographic consequences of this achievement. Finally, we discuss how the localization approach in presence of Wilson loops can capture other interesting observables, such as chiral correlators and the stress tensor one point function, up to a geometry deformation.

- Mikhail Isachenkov, Solving large N double-scaled SYK
Abstract: I will review a method to evaluate correlation functions of certain statistical systems via chord diagrams and apply it to compute correlators in the double-scaled version of SYK model, in particular in its large N limit. The results are exact at all energies and allow to extract corrections to the maximal Lyapunov exponent. Time permitting, I will comment on the suggested relation of this model to a Hamiltonian reduction of quantum particle moving on the non-compact quantum group SU_q(1,1).
