Brane annihilation in non-supersymmetric strings
Riccardo Antonelli, Ivano Basile
In this paper we study non-perturbative instabilities in Anti de-Sitter vacua arising from flux compactifications of string models with broken supersymmetry. In the semi-classical…

On All-Order Higher-Point - Effective Actions
Riccardo Antonelli, Ivano Basile, Ehsan Hatefi
In this paper we derive a class of contributions to all orders in to the effective action of D-brane-anti D-brane systems in Type II String Theory, considering an amplitude in…

AdS Vacuum Bubbles, Holography and Dual RG Flows
Riccardo Antonelli, Ivano Basile, Alessandro Bombini
We explore the holographic properties of non-perturbative vacuum decay in Anti-de Sitter () geometries. To this end, we consider a gravitational theory in a metastabl…
