Every Gromov elliptic domain is meromorphically pseudoconvex
Yuta Kusakabe
We prove that every Gromov elliptic domain in a complex manifold has the following property, which we call meromorphic pseudoconvexity: each boundary point has a neighborhood $…
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…
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…
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…
