6D (1,1) Gauged Supergravities from Orientifold Compactifications
Giuseppe Dibitetto, Jose J. Fernandez-Melgarejo, Masato Nozawa
We study dimensional reductions of M-theory/type II strings down to 6D in the presence of fluxes and spacetime filling branes and orientifold planes of different types. We classify…
de Sitter Cosmology on an expanding bubble
Souvik Banerjee, Ulf Danielsson, Giuseppe Dibitetto +2
Constructing an explicit compactification yielding a metastable de Sitter (dS) vacuum in a UV consistent string theory is an incredibly difficult open problem. Motivated by this is…
vacua and surface defects in massive IIA
Giuseppe Dibitetto, Nicolò Petri
We summarize the results and the ideas in 1707.06152, 1707.06154, 1807.07768 where new warped backgrounds are derived in massive IIA string theory by uplifting exa…
Constructing stable de Sitter in M-theory from higher curvature corrections
Johan Blåbäck, Ulf Danielsson, Giuseppe Dibitetto +1
We consider dimensional reductions of M-theory on with the inclusion of arbitrary metric flux and spacetime filling KK monopoles. With these ing…
