Hidden Sectors in String Theory: Kinetic Mixings, Fifth Forces and Quintessence
Bobby Samir Acharya, Anshuman Maharana, Francesco Muia
Light moduli fields in string compactifications can have interesting implications for particle physics and cosmology. Fifth force bounds impose stringent constraints on the interac…
De Sitter vs Quintessence in String Theory
Michele Cicoli, Senarath de Alwis, Anshuman Maharana +2
De Sitter solutions have been recently conjectured to be incompatible with quantum gravity. In this paper we critically assess the progress and challenges of different mechanisms t…
Moduli Stars
Sven Krippendorf, Francesco Muia, Fernando Quevedo
We explore the possibility that (Bose-Einstein) condensation of scalar fields from string compactifications can lead to long-lived compact objects. Depending on the type of scalar…
Emerging chromo-natural inflation
Valerie Domcke, Ben Mares, Francesco Muia +1
The shift-symmetric coupling of a pseudo-scalar particle driving inflation to gauge fields provides a unique way of probing cosmic inflation. We show for an SU(2) gauge group how a…
