13. A review of the status of dS vacua in string theory

Prof. Thomas Van Riet (Leuven University)

27/05/2021 15:00

I shall review the status of dS vacua in string theory in a (hopefully) pedagogical manner. Most of the talk will be about general principles and constraints. But in order to highlight the intricacies of dS model building I will address some details of the particular KKLT scenario.

14. Holographic routes to de Sitter space

Prof. Francesco Nitti (APC)

27/05/2021 15:40

Constructing cosmological solutions in the context of string theory has been notoriously elusive. In this talk I will discuss, from a bottom up point of view, possible ways of obtaining de Sitter/cosmological geometries based on the gauge/gravity duality. These methods are alternative to the standard route (finding a semiclassical vacuum solution of string theory with an effective...

15. Fast Radio Burst Physics & Cosmology

Prof. Pawan Kumar (U. of Texas, Austin)

27/05/2021 16:20

The detection of a Fast radio burst (FRB) in 2007 was a major unexpected discovery in astronomy in decades. Hunting for FRBs and measuring their physical properties have become one of the leading scientific goals in astronomy. It is well established that many FRBs are located at a distance of several billion lightyears, and therefore they are the brightest known transients in the universe in...
