Brane Nucleation in Supersymmetric Models
Igor Bandos, Jose J. Blanco-Pillado, Kepa Sousa +1
This paper explores the process of vacuum decay in supersymmetric models related to flux compactifications. In particular, we describe these instabilities within supersymmetric Lag…
Universal Class of Type-IIB Flux Vacua with Analytic Mass Spectrum
Jose J. Blanco-Pillado, Kepa Sousa, Mikel A. Urkiola +1
We report on a new class of flux vacua generically present in Calabi-Yau compactifications of type-IIB string theory. At these vacua, the mass spectrum of the complete axio-dilaton…
Towards a complete mass spectrum of type-IIB flux vacua at large complex structure
Jose J. Blanco-Pillado, Kepa Sousa, Mikel A. Urkiola +1
The large number of moduli fields arising in a generic string theory compactification makes a complete computation of the low energy effective theory infeasible. A common strategy…
Nothing is certain in string compactifications
Iñaki García Etxebarria, Miguel Montero, Kepa Sousa +1
A bubble of nothing is a spacetime instability where a compact dimension collapses. After nucleation, it expands at the speed of light, leaving "nothing" behind. We argue that the…
Slepian models for Gaussian Random Landscapes
Jose J. Blanco-Pillado, Kepa Sousa, Mikel A. Urkiola
Phenomenologically interesting scalar potentials are highly atypical in generic random landscapes. We develop the mathematical techniques to generate constrained random potentials,…
First order perturbations of hypersurfaces of arbitrary causal character
Brien C. Nolan, Borja Reina, Kepa Sousa
In this work we study the problem of first order perturbations of a general hypersurface, i.e. with arbitrary causal character at each point. We extend the framework by Mars (Class…
