Journal ArticleDOI
String Axiverse
TL;DR: The existence of axions over a vast mass range from 10-33eV to 10-10eV was investigated in this article, where it was shown that axions in the mass range between 10-28eV and 10-18eV give rise to multiple steps in the matter power spectrum, that will be probed by upcoming galaxy surveys.
Journal ArticleDOI
A natural framework for chaotic inflation.
Nemanja Kaloper,Lorenzo Sorbo +1 more
TL;DR: It is shown that inflation with a quadratic potential occurs naturally in theories where an axionlike field mixes with a 4-form, and the axion can roll slowly towards its minimum, as in the simplest version of chaotic inflation.
Journal ArticleDOI
A Small cosmological constant from a large extra dimension
TL;DR: In this article, a new approach to the cosmological constant problem is proposed, which makes essential use of an extra dimension, and the strong curvature region of the solutions may effectively cut off the size of the extra dimension and give rise to macroscopic 4D gravity.
Journal ArticleDOI
Bent Domain Walls as Braneworlds
TL;DR: In this article, the authors consider domain walls embedded in curved backgrounds as an approximation for braneworld scenarios and give a large class of new exact solutions, exausting the possibilities for describing one and two walls for the cases where the curvature of both the bulk and the wall are locally constant.
Journal ArticleDOI
An ignoble approach to large field inflation
TL;DR: In this paper, the authors study an inflationary model developed by Kaloper and Sorbo, in which the inflaton is an axion with a sub-Planckian decay constant, whose potential is generated by mixing with a topological 4-form field strength.
