The Cosmological Constant and Dark Dimensions from Non-Supersymmetric Strings
Emilian Dudas, Susha Parameswaran, Marco Serra
We present a string theory construction in which the particle physics contributions to the one-loop vacuum energy exactly cancel, whilst the gravitational contributions are suppres…

A guide to frames, 's, scales and corrections in string compactifications
Bruno Valeixo Bento, Dibya Chakraborty, Susha Parameswaran +1
This note is intended to serve as a reference for conventions used in the literature on string compactifications, and how to move between them, collected in a single and easy-to-fi…

Cosmological tests of quintessence in quantum gravity
Sukannya Bhattacharya, Giulia Borghetto, Ameek Malhotra +3
We use a suite of the most recent cosmological observations to test models of dynamical dark energy motivated by quantum gravity. Specifically, we focus on hilltop quintessence sce…
