On the distribution of stable de Sitter vacua
Ulf Danielsson, Giuseppe Dibitetto
The possible existence of (meta-) stable de Sitter vacua in string theory is of fundamental importance. So far, there are no fully stable solutions where all effects are under pert…
The SU(3)-invariant sector of new maximal supergravity
A. Borghese, G. Dibitetto, A. Guarino +2
We investigate the SU(3)-invariant sector of the one-parameter family of SO(8) gauged maximal supergravity that has been recently proposed. To this end, we construct the N=2 trunca…
Gauged Supergravities and the Physics of Extra Dimensions
Giuseppe Dibitetto
This thesis analyses gauged supergravities in various dimensions and their possible origin from compactifications of string theory. In the effective description the fluxes appear i…
Duality orbits of non-geometric fluxes
G. Dibitetto, J. J. Fernandez-Melgarejo, D. Marques +1
Compactifications in duality covariant constructions such as generalised geometry and double field theory have proven to be suitable frameworks to reproduce gauged supergravities c…
Exceptional Flux Compactifications
Giuseppe Dibitetto, Adolfo Guarino, Diederik Roest
We consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gauged D=4 supergravity. This enables one…
