Control problem of de-Sitter spacetime in large scale flux landscape

Time：2023-05-30 Tue 10:00-12:00

Venue：A3-2-201

Organizer：Hongfei Shu, Hao Zou, Ruidong Zhu

Speaker：Xin Gao Sichuan University

Abstract

In this talk, I will discuss recent advances in string landscape and swampland. First, I will clarify various corrections in string compactifications and their implications in 4D N=1 SUGRA language. Next, I will focus on warping correction and parameter control issues in achieving de-Sitter space in both KKLT and Large Volume Scenarios. Finally, I will examine the feasibility of these constraints in large scale of Calabi-Yau compactifications, including construction of orientifold Calabi-Yau database and the use of Machine Learning techniques to create new geometries and find orientifold string vacua.

Complex saddles of three-dimensional de Sitter gravity via holography
AbstractIt would be useful to deal with complex geometry when examining quantum gravity as in the case of no-boundary proposal by Hartle and Hawking. However, there would be too many saddles for complexified gravity, and it is necessary to determine which are allowable geometries in the sense of Witten. We consider three-ddimensional gravity theory with positive consmological constant described...
