Nothing really matters

Journal of High Energy Physics, 2020
We study non-perturbative instabilities of AdS spacetime in General Relativity with a cosmological constant in arbitrary dimensions. In this simple setup we explicitly construct a class of gravitational instantons generalizing Witten’s bubble of nothing.

Eluding SUSY at every genus on stable closed string vacua [PDF]

, 2011
In closed string vacua, ergodicity of unipotent flows provide a key for relating vacuum stability to the UV behavior of spectra and interactions. Infrared finiteness at all genera in perturbation theory can be rephrased in terms of cancelations involving

Moduli stabilization in type IIB orientifolds at h2,1 = 50

Journal of High Energy Physics, 2023
We study moduli stabilization in Calabi-Yau orientifold compactifications of type IIB string theory with O3- and O7-planes. We consider a Calabi-Yau three-fold with Hodge number h 2,1 = 50 and stabilize all axio-dilaton and complex-structure moduli by ...

Holography for Non-Critical Superstrings [PDF]

, 1999
We argue that a class of ``non-critical superstring'' vacua is holographically related to the (non-gravitational) theory obtained by studying string theory on a singular Calabi-Yau manifold in the decoupling limit $g_s\to 0$.

Lectures on Superstring and M Theory Dualities [PDF]

, 1996
These lectures begin by reviewing the evidence for S duality of the toroidally compactified heterotic string in 4d that was obtained in the period 1992--94.

On Four Dimensional N=1 Type I Compactifications [PDF]

, 1998
We consider four dimensional N=1 supersymmetric Type I compactifications on toroidal orbifolds T^6/G. In particular, we focus on the Type I vacua which are perturbative from the orientifold viewpoint, that is, on the compactifications with well defined ...

Bound States Of Strings And $p$-Branes [PDF]

, 1995
The recent discovery of an explicit conformal field theory description of Type II $p$-branes makes it possible to investigate the existence of bound states of such objects.

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.

New de Sitter solutions of 10d type IIB supergravity

Journal of High Energy Physics, 2020
We find and study 17 new de Sitter solutions of ten-dimensional (10d) type IIB supergravity with intersecting D 5-branes and orientifold O 5-planes, as well as a new Minkowski one.

Systematics of type IIB moduli stabilisation with odd axions

Journal of High Energy Physics, 2022
Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua.
