1. 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 [...]

2. De Sitter vacua from a D-term generated racetrack potential in hypersurface Calabi-Yau compactifications / Braun, Andreas ; Rummel, Markus ; Sumitomo, Yoske ; Valandro, Roberto
In [1] a mechanism to fix the closed string moduli in a de Sitter minimum was proposed: a D-term potential generates a linear relation between the volumes of two rigid divisors which in turn produces at lower energies a race-track potential with de Sitter minima at exponentially large volume. [...]

4. De Sitter vacua from a D-term generated racetrack uplift / Sumitomo, Yoske ; Rummel, Markus
We propose an uplift mechanism using a structure of multi-Kähler moduli dependence in the F-term potential of type IIB string theory compactifications. [...]
