Black Holes, Branes and Superconformal Symmetry

, 1999
The main focus of this lecture is on extended objects in adS*S bosonic backgrounds with unbroken supersymmetry. The backgrounds are argued to be exact, special consideration are given to the non-maximal supersymmetry case.

Scaling limits of dS vacua and the swampland

Journal of High Energy Physics, 2019
We discuss the properties of massive type IIA flux compactifications. In particular, we investigate in which case one can obtain dS vacua at large volume and small coupling.

Dual Gauged Supergravities [PDF]

, 2007
We shall review a novel formulation of four dimensional gauged supergravity which is manifestly covariant with respect to the non-perturbative electric-magnetic duality symmetry transformations of the ungauged theory, at the level of the equations of ...

Orientifold Calabi-Yau threefolds: divisor exchanges and multi-reflections

Journal of High Energy Physics
Using the Kreuzer-Skarke database of 4-dimensional reflexive polytopes, we systematically constructed a new database of orientifold Calabi-Yau threefolds with h 1,1(X) ≤ 12.

The gravitational sector of 2d (0, 2) F-theory vacua

Journal of High Energy Physics, 2017
F-theory compactifications on Calabi-Yau fivefolds give rise to two-dimensional N = (0, 2) supersymmetric field theories coupled to gravity. We explore the dilaton supergravity defined by the moduli sector of such compactifications.

Stokes Phenomena and Quantum Integrability in Non-critical String/M Theory

, 2011
We study Stokes phenomena of the k \times k isomonodromy systems with an arbitrary Poincar\'e index r, especially which correspond to the fractional-superstring (or parafermionic-string) multi-critical points (\hat p,\hat q)=(1,r-1) in the k-cut two ...

De Sitter vacua in no-scale supergravity

Journal of High Energy Physics, 2018
No-scale supergravity is the appropriate general framework for low-energy effective field theories derived from string theory. The simplest no-scale Kähler potential with a single chiral field corresponds to a compactification to flat Minkowski space ...

A universal tachyon in nearly no-scale de Sitter compactifications

Journal of High Energy Physics, 2018
We investigate de Sitter solutions of N=1 $$ \mathcal{N}=1 $$ supergravity with an F-term scalar potential near a no-scale Minkowski point, as they may in particular arise from flux compactifications in string theory.
