Taxonomy of type II orientifold flux vacua in 3D
Álvaro Arboleya, Gabriele Casagrande, Adolfo Guarino +1
We complete the study initiated in \cite{Arboleya:2024vnp} and investigate three-dimensional (3D) flux vacua of type II orientifold reductions on twisted tori that include a single…
Linear and nonlinear supersymmetry in field and string theory
Gabriele Casagrande
This Ph.D. thesis investigates effective field and string theories in which supersymmetry is realized and broken in various ways. Chapter 1 addresses effective theories with nonlin…
A unique coupling of the massive spin-2 field to supergravity
Guillaume Bossard, Gabriele Casagrande, Emilian Dudas +1
We show that the coupling of a massive spin-2 field to undeformed N=1 supergravity in four dimensions is unique, leading to a specific non-minimal coupling to the Riemann tensor. T…
Twisted Orientifold planes and S-duality without supersymmetry
Guillaume Bossard, Gabriele Casagrande, Emilian Dudas
We construct a novel orientifold of type IIB string theory that breaks all supersymmetries. It is a closed string theory without open sector and it can be understood as a Scherk-Sc…
On energy and particle production in cosmology: the particular case of the gravitino
Gabriele Casagrande, Emilian Dudas, Marco Peloso
It is well-known that the number of particles produced in cosmology, commonly defined in the literature from the Fock space of the instantaneous hamiltonian of the canonically norm…
Causality constraints on nonlinear supersymmetry
Quentin Bonnefoy, Gabriele Casagrande, Emilian Dudas
It is well-known that gravitino propagation in standard supergravities is free of any causality problems. However, two issues related to gravitino propagation were recently uncover…
