Late-Time Correlators and Complex Geodesics in de Sitter Space
Lars Aalsma, Mir Mehedi Faruk, Jan Pieter van der Schaar +2
We study two-point correlation functions of a massive free scalar field in de Sitter space using the heat kernel formalism. Focusing on two operators in conjugate static patches we…
Resurgence of a de Sitter Glauber-Sudarshan State: Nodal Diagrams and Borel Resummation
Suddhasattwa Brahma, Keshav Dasgupta, Mir-Mehedi Faruk +4
We show that an explicit construction of a four-dimensional de Sitter space may be performed using a diagrammatic approach via nodal diagrams emanating from the path integral repre…
The inheritance of energy conditions: Revisiting no-go theorems in string compactifications
Heliudson Bernardo, Suddhasattwa Brahma, Mir Mehedi Faruk
One of the fundamental challenges in string theory is to derive realistic four-dimensional cosmological backgrounds from it despite strict consistency conditions that constrain its…
