Logarithmic loop corrections, moduli stabilisation and de Sitter vacua in string theory
Ignatios Antoniadis, Yifan Chen, George K. Leontaris
We study string loop corrections to the gravity kinetic terms in type IIB compactifications on Calabi-Yau threefolds or their orbifold limits, in the presence of -branes and or…
Moduli Stabilization and Inflation in Type IIB/F-theory
Ignatios Antoniadis, Yifan Chen, George K. Leontaris
In the first part of this talk, a short overview of the ongoing debate on the existence of de Sitter vacua in string theory is presented. In the second part, the moduli stabilisati…
Inflation from the internal volume in type IIB/F-theory compactification
Ignatios Antoniadis, Yifan Chen, George K. Leontaris
We study cosmological inflation within a recently proposed framework of perturbative moduli stabilisation in type IIB/F theory compactifications on Calabi-Yau threefolds. The stabi…
Stripping a supermultiplet of all but one scalar: a microscopic view
Karim Benakli, Yifan Chen
We explain how a single scalar degree of freedom can be obtained from projecting out all the other components of a chiral superfield using simple operators in the microscopic theor…
Perturbative moduli stabilisation in type IIB/F-theory framework
Ignatios Antoniadis, Yifan Chen, George K. Leontaris
We propose a new mechanism of (geometric) moduli stabilisation in type IIB/F-theory four-dimensional compactifications on Calabi-Yau manifolds, in the presence of 7-branes, that do…
Minimal constrained superfields and the Fayet-Iliopoulos model
Karim Benakli, Yifan Chen, Mark D. Goodsell
We show how the necessary constraints to project out all the components of a chiral superfield except for some scalar degrees of freedom originate from simple operators in the micr…
