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…
Coherent States in M-Theory: A Brane Scan using the Taub-NUT
Joydeep Chakravarty, Keshav Dasgupta, Diksha Jain +3
The Taub-NUT geometry corresponds to the Kaluza-Klein monopole solution of M-theory and on dimension reduction along the Taub-NUT circle direction it becomes the D6 brane of type I…
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…
The Generalized OTOC from Supersymmetric Quantum Mechanics: Study of Random Fluctuations from Eigenstate Representation of Correlation Functions
Kaushik Y. Bhagat, Baibhab Bose, Sayantan Choudhury +7
The concept of out-of-time-ordered correlation (OTOC) function is treated as a very strong theoretical probe of quantum randomness, using which one can study both chaotic and non-c…
