AdS from M-branes at conical singularities
Giuseppe Dibitetto, Nicolò Petri
M-theory is known to possess supersymmetric solutions where the geometry is warped over a Riemann surface . The simplest examples in thi…
Out of the Swampland with Multifield Quintessence?
Michele Cicoli, Giuseppe Dibitetto, Francisco G. Pedro
Multifield models with a curved field space have already been shown to be able to provide viable quintessence models for steep potentials that satisfy swampland bounds. The simples…
New accelerating solutions in late-time cosmology
Michele Cicoli, Giuseppe Dibitetto, Francisco G. Pedro
Dark energy models can be seen as dynamical systems. In this paper we show that multi-field models with a curved field space give rise to new critical points and we analyse their s…
Nothing really matters
Giuseppe Dibitetto, Nicolò Petri, Marjorie Schillo
We study non-perturbative instabilities of AdS spacetime in General Relativity with a cosmological constant in arbitrary dimensions. In this simple setup we explicitly construct a…
Holographic Description of M-branes via AdS
Giuseppe Dibitetto, Yolanda Lozano, Nicolò Petri +1
We study solutions in type IIB string theory arising from D1 -- D3 -- NS5 brane intersections. These backgrounds enjoy sixteen supe…
