We propose a holographic description of four-dimensional single-scalar inflationary
universes, and show how cosmological observables, such as the primordial power …

A bstract We formulate a renormalisation procedure for IR divergences of tree-level in-in late-
time de Sitter (dS) correlators. These divergences are due to the infinite volume of spacetime …

A bstract The usual theory of inflation breaks down in eternal inflation. We derive a dual
description of eternal inflation in terms of a deformed Euclidean CFT located at the threshold …

This work deals with braneworld models driven by real scalar fields with nonstandard
dynamics. We develop the first-order formalism for models with standard gravity but with the …

We present a holographic description of four-dimensional single-scalar inflationary
universes in terms of a three-dimensional quantum field theory (QFT). The holographic …

The target space geometry of abelian vector multiplets in N= 2 theories in four and five
space–time dimensions is called special geometry. It can be elegantly formulated in terms of …

A bstract We construct new solutions of ten-dimensional supergravity with sixteen super-
charges which describe the backreaction of Dp-branes with spherical worldvolume. These …

We define and study projective special para-Kähler manifolds and show that they appear as
target manifolds when reducing five-dimensional vector multiplets coupled to supergravity …

A bstract We argue that a type IIB Euclidean supergravity solution of the form ℝ× S 1× 𝕋 8
with imaginary self-dual F 1 flux through ℝ× S 1 belongs to the chain of AdS d× S d× 𝕋 10 …

We realize the domain-wall/cosmology correspondence for (pseudo) supersymmetric
domain walls (cosmologies) in the context of four-dimensional supergravity. The OSp (2| 4) …
