[phys4phys] Group for Gravitation, Particle and Fields seminar, Friday 9 June 2023

[Marija Dimitrijevic Ciric]

Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Friday, 9 June 2023 at 11:00 
at the Institute of Physics, lecture hall 360.


The talk entitled

Holographic Aspects of Even-Dimensional Topological Gravity

will be given by Dusan Djordjevic (Faculty of Physics, University of 
Belgrade).

Abstract: Despite being formulated over 30 years ago, the topological 
gauge theory of gravity in an even number of space-time dimensions has 
received limited attention. In this talk, we will consider this theory 
(with the AdS gauge group) in the setup of holographic duality. First, 
we will compute the holographic one-point functions. The fact that 
one-point function of a spin current generally does not vanish opens up 
a possibility of application in the field of spin systems in three 
space-time dimensions. Then, we will further investigate some bulk 
semiclassical geometries and discuss them in the light of holography. 
Finally, we will discuss the two-point function in the dual-field theory 
using the Wilson line-like presentation of a probe point particle in the 
bulk.
