1. Postinflationary scalar tensor cosmology and inflationary parameters / Maharana, Anshuman ; Zavala, Ivonne
Scalar fields provide attractive modifications of pre-BBN cosmology, which have interesting implications for dark matter abundances. [...]

2. Inflating Kahler moduli and primordial magnetic fields / Aparicio, Luis ; Maharana, Anshuman
We study the production of primordial magnetic fields in inflationary models in type IIB string theory where the role of the inflaton is played by a Kahler modulus. [...]

3. Accidental Kähler moduli inflation / Maharana, Anshuman ; Rummel, Markus ; Sumitomo, Yoske
We study a model of accidental inflation in type IIB string theory where inflation occurs near the inflection point of a small Kähler modulus [...]

4. Moduli vacuum misalignment and precise predictions in string inflation / Cicoli, Michele ; Dutta, Koushik ; Maharana, Anshuman ; Quevedo, Fernando
The predictions for all the cosmological observables of any inflationary model depend on the number of e-foldings which is sensitive to the post-inflationary history of the universe. [...]

5. Inflationary predictions and moduli masses / Das, Kumar ; Dutta, Koushik ; Maharana, Anshuman
A generic feature of inflationary models in supergravity/string constructions is vacuum misalignment for the moduli fields. [...]

8. Sequestered de Sitter string scenarios: soft-terms / Aparicio, Luis ; Cicoli, Michele ; Krippendorf, Sven ; Maharana, Anshuman ; et al
We analyse soft supersymmetry breaking in type IIB de Sitter string vacua after moduli stabilisation, focussing on models in which the Standard Model is sequestered from the supersymmetry breaking sources and the spectrum of soft-terms is hierarchically smaller than the gravitino mass m 3/2 . [...]

9. N-flation with hierarchically light axions in string compactifications / Cicoli, Michele ; Dutta, Koushik ; Maharana, Anshuman
We propose a possible embedding of axionic N-flation in type IIB string compactifications where most of the Kähler moduli are stabilised by perturbative effects, and so are hierarchically heavier than the corresponding N≫ 1 axions whose collective dynamics drives inflation. [...]

10. A note on the magnitude of the flux superpotential / Michele Cicoli ; Joseph P. Conlon ; Anshuman Maharana ; Fernando Quevedo
The magnitude of the flux superpotential W flux plays a crucial role in determining the scales of IIB string compactifications after moduli stabilisation. [...]
