[hep-th] Balkan String Webinar – February 13 14:30 CET – Nikolay Bobev

[Mihailo Čubrović]

Dear colleagues,

Next Friday, February 13,
at 14:30 CET (NOTICE THE TIME!),
Nikolay Bobev (KU Leuven, Belgium) will give an online talk within the 
Balkan String Webinar series.

Title: Precision Holography for Dp-branes

Abstract: I will discuss precision holography for the non-conformal SYM 
theories arising on the worldvolume of coincident Dp-branes. I will show 
how the free energy of the planar SYM theory on the round sphere and the 
expectation values of fundamental BPS Wilson loops can be computed 
explicitly by utilizing supersymmetric localization. I will then present 
a class of supergravity backgrounds that capture the backreaction of 
spherical Dp-branes and provide a holographic description of the SYM 
theory. I will show that the supergravity calculations of the free 
energy and the Wilson loop expectation value are in precise agreement 
with the supersymmetric localization results. Finally, I will exploit 
the scaling similarity property of the Dp-brane supergravity solutions 
to derive simple Witten diagram rules for the calculation of n-point 
correlation functions and will show how to explicitly compute 2pt- and 
3pt-functions. This leads to explicit results for the 2pt- and 
3pt-functions of scalar BPS operators in the planar strongly-coupled SYM 
theory, including the cases of the BFSS model and the 3d maximally 
supersymmetric YM theory, that could be tested using lattice QFT 
methods.
