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…

Relativistic minimization with constraints: A smooth trip to Alpha Centauri
Riccardo Antonelli, Alexander R. Klotz
We consider the relativistic generalization of the problem of the "least uncomfortable" linear trajectory from point A to point B. The traditional problem minimizes the time-integr…
