Seven-Disk Manifold, alpha-attractors and B-modes

, 2016
Cosmological alpha-attractor models in \cN=1 supergravity are based on hyperbolic geometry of a Poincar\'e disk with the radius square {\cal R}^2=3\alpha. The predictions for the B-modes, r\approx 3\alpha {4\over N^2}, depend on moduli space geometry and

Dilaton Weyl multiplets for N $$ \mathcal{N} $$ = 3 conformal supergravity in four dimensions

Journal of High Energy Physics
We construct a dilaton Weyl multiplet for N $$ \mathcal{N} $$ = 3 conformal supergravity in four dimensions. We couple an on-shell vector multiplet to the standard Weyl multiplet and use the field equations of the vector multiplet to replace some of the ...

Linearised actions for N $$ \mathcal{N} $$ -extended (higher-spin) superconformal gravity

Journal of High Energy Physics, 2019
The off-shell actions for N $$ \mathcal{N} $$ -extended conformal supergravity theories in three dimensions were formulated in [1, 2] for 1 ≤ N $$ \mathcal{N} $$ ≤ 6 using a universal approach.

Supergravity on R4 x S1/Z2 and singular Calabi-Yaus

, 2008
We discuss the moduli space singularities that are generally present in five-dimensional vector-coupled supergravity on a spactime of the form R4 x S1/Z2, with vector fields surviving on the Z2 fixed planes.

T-duality across non-extremal horizons

Journal of High Energy Physics
When applying T-duality to a generic, non-extreme Killing horizon, T-duality is spacelike on one side and timelike on the other. We show, using simple examples from four-dimensional Einstein-Maxwell theory, that the image of the horizon is a singularity ...

Inflation in R2 supergravity with non-minimal superpotentials

Physics Letters B, 2015
We investigate the cosmological inflation in a class of supergravity models that are generalizations of non-supersymmetric R2 models. Although such models have been extensively studied recently, especially after the launch of the PLANCK and BICEP2 data ...
