Fat inflatons, large turns and the η-problem
TL;DR: In this paper, it is shown that a successful period of inflation driven by a single or several scalar fields requires a specific hierarchy of masses given by a specific heavy field that might be integrated out if it satisfies suitable conditions.

Fat Inflatons, Large Turns and the $\eta$-problem
TL;DR: In this article, it is shown that a successful period of inflation driven by a single or several scalar fields requires a specific hierarchy of masses given by a specific heavy field, where the turning rate of the inflationary trajectory is larger than one.

A New de Sitter Solution with a Weakly Warped Deformed Conifold
TL;DR: In this article, the authors studied moduli stabilisation for type IIB flux compactifications that include a warped throat region corresponding to a warped deformed conifold, with an anti-D3-brane sitting at its tip.

Dark Energy in String Theory
TL;DR: In this paper, the authors consider various candidate supergravity potentials, motivated by string theory, including single-field Kahler potentials for bulk and local moduli, and leading superpotentials of the form $W = W_0 + A e^{-a \Phi}$ or $W= W_ 0 + A \phi^p.
