A Computational Companion to Transient de Sitter and Quasi de Sitter States in SO(32) and E_8 X E_8 Heterotic String Theories I: Formalisms

Archana Maji

We construct four-dimensional de Sitter space as an excited state, rather than as a vacuum configuration, in type IIB, heterotic SO(32), and heterotic E_8 \times E_8 string theorie…

Transient de Sitter and Quasi de Sitter States in SO(32) and E_8 x E_8 Heterotic String Theories

Keshav Dasgupta, Suddhasattwa Brahma, Bohdan Kulinich +3

One of the long-standing puzzles in string theory has been on the existence of a four-dimensional de Sitter and quasi de Sitter configurations, the latter being defined with a temp…

Flat connections at infinity on knot surgery manifolds

Aditya Dwivedi, Archana Maji, Dmitry Noshchenko +1

Chern-Simons theory on a closed 3-manifold is one of the most interesting, yet tractable examples of a QFT. On one hand, its non-perturbative structure is no…

de Sitter Excited State in Heterotic E_8 x E_8 Theory

Suddhasattwa Brahma, Keshav Dasgupta, Bohdan Kulinich +3

We devise a novel duality sequence to study late-time cosmology in the heterotic E_8 x E_8 setup of Horava and Witten with dynamical walls that are moving towards each other. Surpr…

de Sitter State in Heterotic String Theory

Stephon Alexander, Keshav Dasgupta, Archana Maji +2

Recent no-go theorems have ruled out four-dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well-defined Wilsonian effective act…

Late time dynamics in SUSY saddle-dominated scrambling through higher-point OTOC

Rathindra Nath Das, Sourav Dutta, Archana Maji

In this article, we study the scrambling dynamics in supersymmetric quantum mechanical systems. The eigenstate representation of such supersymmetric systems allows us to present an…
