Fuzzy Dark Matter Candidates from String Theory
Michele Cicoli, Veronica Guidetti, Nicole Righi +1
String theory has been claimed to give rise to natural fuzzy dark matter candidates in the form of ultralight axions. In this paper we revisit this claim by a detailed study of how…
Systematics of type IIB moduli stabilisation with odd axions
Michele Cicoli, Andreas Schachner, Pramod Shukla
Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua. In particular, odd moduli arising…
On the Search for Low
Igor Broeckel, Michele Cicoli, Anshuman Maharana +2
The magnitude of the vacuum expectation value of the Gukov-Vafa-Witten superpotential plays a central role in the phenomenology of type IIB flux compactifications. Recent a…
A Fake Instability in String Inflation
Michele Cicoli, Veronica Guidetti, Francesco Muia +2
In type IIB Fibre Inflation models the inflaton is a Kaehler modulus which is kinetically coupled to the corresponding axion. In this setup the curvature of the field space induces…
On the choice of entropy variables in multifield inflation
Michele Cicoli, Veronica Guidetti, Francesco Muia +2
We discuss the usefulness and theoretical consistency of different entropy variables used in the literature to describe isocurvature perturbations in multifield inflationary models…
Systematics of the Expansion in F-Theory
Michele Cicoli, Fernando Quevedo, Raffaele Savelli +2
Extracting reliable low-energy information from string compactifications notoriously requires a detailed understanding of the UV sensitivity of the corresponding effective field th…
