Fluxes in exceptional field theory and threebrane sigma-models

Journal of High Energy Physics, 2019
Starting from a higher Courant bracket associated to exceptional generalized geometry, we provide a systematic derivation of all types of fluxes and their Bianchi identities for four-dimensional compactifications of M-theory.

Helical phase inflation via non-geometric flux compactifications: from natural to starobinsky-like inflation [PDF]

, 2015
A bstractWe show that a new class of helical phase inflation models can be simply realized in minimal supergravity, wherein the inflaton is the phase component of a complex field and its potential admits a deformed helicoid structure.

Dynamics of warped flux compactifications with backreacting antibranes [PDF]

, 2014
We revisit the effective low-energy dynamics of the volume modulus in warped flux compactifications with anti-D3-branes in order to analyze the prospects for meta-stable de Sitter vacua and brane inflation along the lines of KKLT/KKLMMT.

Generalised Geometry and Flux Vacua

, 2015
This note discusses the connection between generalised geometry and flux compactifications of string theory. Firstly, we explain in a pedestrian manner how the supersymmetry constraints of type II ${\mathcal{N}}=1$ flux compactifications can be restated ...

Charting the landscape of N=4 flux compactifications [PDF]

, 2011
We analyse the vacuum structure of isotropic Z_2 x Z_2 flux compactifications, allowing for a single set of sources. Combining algebraic geometry with supergravity techniques, we are able to classify all vacua for both type IIA and IIB backgrounds with ...

Moduli identification methods in Type II compactifications

Journal of High Energy Physics, 2018
Recent work on four dimensional effective descriptions of the heterotic string has identified the moduli of such systems as being given by kernels of maps between ordinary Dolbeault cohomology groups.

Sharpening the boundaries between flux landscape and swampland by tadpole charge

Journal of High Energy Physics, 2021
We investigate the vacuum structure of four-dimensional effective theory arising from Type IIB flux compactifications on a mirror of the rigid Calabi-Yau threefold, corresponding to a T-dual of the DeWolfe-Giryavets-Kachru-Taylor model in Type IIA flux ...
