Seminars

During the semester we have a high energy seminar and a lunch seminar. In addition to these two seminars we participate in a joint theoretical high energy theory seminar in Newe Shalom. The joint seminar takes place on Tuesdays from 10:30 until 13:30 and includes two talks and lunch. This seminar is attended by the high energy groups of all the Israeli institutions and usually attracts a crowd of roughly twenty participants.

“Turbulence, CFT and Random Geometry” We propose a field theory description of steady state incompressible fluid turbulence at the inertial range of scales in a general number of space dimensions. The theory consists of a[...]

Title: Exact results for 5d SCFTs with holographic duals in Type IIB Abstract: Five-dimensional superconformal field theories (5d SCFTs) play an interesting role in the general understanding of quantum field theory. They provide strongly-coupled UV[...]

Title: Branes and the Swampland Abstract: In this talk, I will discuss consistency of N=(1,0) supergravity theories in 10d and in 6d by using 1/2 BPS string probes. Such string probes are expected to exist due to completeness of the spectrum of charged branes in a gravitational theory.I will show that some of the theories with N=(1,0) supersymmetry in 10d and 6d, which are otherwise consistent looking, belong to the Swampland by showing that the central charge on the string probes in those gravity theories are too small to host unitary representationsof the current algebra for the bulk gauge symmetries.

Title “AdS/CFT at finite string coupling”



Abstract

We consider the S-matrix in Type IIB/IIA string theory, and compare it to correlators of the stress tensor multiplet in various holographic CFTs. On flat space, the leading small momentumcorrections to these S-matrices are protected and known at finite string coupling. At finite string coupling, Type IIB on AdS_5 x S_5 is dual to 4dN=4 SYM at large N and finite complexified coupling tau, while Type IIA on AdS_4 x S^7/Z_k is dual to 3d ABJM with Chern-Simons level k at large N and fixed N/k^5. In each case, we computethe CFT correlator to several orders in 1/N using supersymmetric localization, and find that it matches the known S-matrix in the flat space limit, which is the first non-perturbative (in string coupling) check of AdS/CFT. In the Type IIB case, the 1/N coefficientsare modular functions of tau under S-duality, which receive infinite instanton corrections. In the Type IIA case, the 1/N coefficients receive no instanton corrections, and interpolate from M-theory at small k (large string coupling) to Type IIA at large k(weak string coupling)
