R7-branes and AdS solutions in type IIB
Giuseppe Dibitetto, Cameron Gibson, Nicolò Petri +1
We consider the recently found backgrounds in type IIB supergravity. We start by reviewing the solutions in a more convenient set of coordinates, which allows us t…
Integrable models of inflation beyond slow-roll
M. Bianchi, G. Dibitetto, J. F. Morales +1
We propose a novel analytic approach to the study of multi-component FLRW cosmologies and their perturbations. The dynamics is triggered by a single scalar field with a scalar pote…
AdS solutions in type II supergravities
Giuseppe Dibitetto, Nicolò Petri
We present new solutions in type II supergravities describing AdS geometries warped over an interval. In type IIB, we construct an analytic family of backgrounds supported by a…
solutions in axio-dilaton gravity
Giuseppe Dibitetto, Nicolò Petri
We study non-supersymmetric solutions in the context of dimensional gravity coupled to an axio-dilaton with arbitrary runaway potential for the dil…
7D (non-)susy vacua & DWs from dynamical open strings
Valentina Bevilacqua, Giuseppe Dibitetto, Giuseppe Sudano
Warped compactifications of massive type IIA supergravity on a 3-sphere with spacetime-filling O6/D6 sources are known to admit a half-maximal gauged supergravity description in 7D…
Non-SUSY DW's in ISO(7) gauged supergravity
Nathan Bagshaw, Giuseppe Dibitetto
We consider 4D maximal gauged supergravity, which is known to arise from a consistent truncation of massive IIA supergravity on a six-sphere. Within its $\mathrm{…
