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…
On (A)dS Solutions from Scherk-Schwarz Orbifolds
Susha Parameswaran, Marco Serra
We investigate the existence of dS vacua in supersymmetry-breaking Scherk-Schwarz toroidal compactifications of type II string theory, using the well-understood ingredients of curv…
Exponential Quintessence: curved, steep and stringy?
David Andriot, Susha Parameswaran, Dimitrios Tsimpis +2
We explore the possibility that our universe's current accelerated expansion is explained by a quintessence model with an exponential scalar potential, , keepi…
De Sitter vacua -- when are `subleading corrections' really subleading?
Bruno Valeixo Bento, Dibya Chakraborty, Susha Parameswaran +1
We consider various string-loop, warping and curvature corrections that are expected to appear in type IIB moduli stabilisation scenarios. It has recently been argued, in the conte…
String Cosmology: from the Early Universe to Today
Michele Cicoli, Joseph P. Conlon, Anshuman Maharana +3
We review applications of string theory to cosmology, from primordial times to the present-day accelerated expansion. Starting with a brief overview of cosmology and string compact…
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…
