CMB Injection Bounds on Moduli Fields
Naman Agarwal, Andrew R. Frey, Ratul Mahanta +3
Light scalar fields with gravitational strength interactions (moduli) are ubiquitous in string, supergravity, and extra-dimensional models. If produced in the early universe with l…
Axio-Dilaton Dark Energy: A Dynamical Systems and Bayesian Inference Analysis
Mario Ramos-Hamud, Gabriela García-Arroyo, Fernando Quevedo +1
We initiate a systematic cosmological investigation of an axio-dilaton system governed by a curved field-space metric as generically motivated by supergravity and string compactifi…
Back to the origins of brane-antibrane inflation
Michele Cicoli, Christopher Hughes, Ahmed Rakin Kamal +4
We study a new framework for brane-antibrane inflation where moduli stabilisation relies purely on perturbative corrections to the effective action. This guarantees that the model…
Gravitational Waves from High Temperature Strings
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +2
We study finite temperature effects in string cosmology and their potential gravitational wave signature. Expanding on our recent work arXiv:2310.11494 , we consider a general conf…
String Thermodynamics In and Out of Equilibrium: Boltzmann Equations and Random Walks
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +3
We revisit the study of string theory close to the Hagedorn temperature with the aim towards cosmological applications. We consider interactions of open and closed strings in a gas…
Higher Derivative Corrections to String Inflation
Michele Cicoli, Matteo Licheri, Pellegrino Piantadosi +2
We quantitatively estimate the leading higher derivative corrections to supergravity derived from IIB string compactifications and study how they may affect modul…
