Massive type 0A string theory and M-theory
Niccolò Cribiori, Andriana Makridou, Salvatore Raucci
We propose an M-theory origin for the two massive deformations of type 0A string theory by extending Hull's realization of massive type IIA in the context of a recent proposal for…
Type IIA on Spin(7) manifolds with fluxes
Niccolò Cribiori, Arda Hasar, Thomas Van Riet +1
We initiate a systematic study of compactifications of type II string theory to two dimensions on Ricci-flat spaces with fluxes and sources. We derive universal constraints on such…
Scale-separated vacua with extended supersymmetry
Niccolò Cribiori, Fotis Farakos, Alexandros Zarafonitis
We propose the first examples of scale-separated vacua with extended supersymmetry. They arise as circle compactifications of four-dimensional vacua of massive type IIA supergravit…
A domain wall bound on anti-de Sitter vacua
Niccolò Cribiori, Antonia Paraskevopoulou, Thomas Van Riet
We consider anti-de Sitter flux vacua interpolated by flux-changing domain walls. Demanding that the tension of such a domain wall be above the ultraviolet cutoff of the effective…
Cosmological constraints from UV/IR mixing
Niccolò Cribiori, Flavio Tonioni
Holography and entropy bounds suggest that the ultraviolet (UV) and infrared (IR) cutoffs of gravitational effective theories are related to one another as a form of UV/IR mixing.…
Bulk/boundary Modular Quintessence and DESI
Luis A. Anchordoqui, Ignatios Antoniadis, Niccolò Cribiori +4
The latest DESI DR2 results, when combined with other independent cosmological data on the Cosmic Microwave Background and supernovas, suggest a preference for dynamical dark energ…
Scale separation, rolling solutions and entropy bounds
David Andriot, Niccolò Cribiori, Thomas Van Riet
We revisit scale separation for compactifications of ten- and eleven-dimensional supergravity. For cosmological solutions rolling down flux-generated potentials, we observe that sc…
String dualities and modular symmetries in supergravity: a review
Niccolò Cribiori, Dieter Lust
We review the remarkable interplay between modular symmetries and supergravity, which has led to major advances in both physics and mathematics in recent decades. Our focus will be…
On scale-separated supersymmetric AdS flux vacua
N. Cribiori, F. Farakos, N. Liatsos
We argue that scale-separated AdS vacua with at least two preserved supercharges cannot arise from flux compactifications in a regime of computational control. We deduce this b…
Reflections on an M-theoretic Emergence Proposal
Ralph Blumenhagen, Niccolò Cribiori, Aleksandar Gligovic +1
In a pedagogical manner, we review recent developments in the investigation of the Emergence Proposal. Although it is fair to say that this idea is still at an exploratory level an…
Emergence of -terms in M-theory
Ralph Blumenhagen, Niccolò Cribiori, Aleksandar Gligovic +1
It has been recently suggested that the strong Emergence Proposal is realized in M-theory limits by integrating out all light towers of states with a typical mass scale not larger…
Minimal Black Holes and Species Thermodynamics
Ivano Basile, Niccolò Cribiori, Dieter Lust +1
The species scale provides a lower bound on the shortest possible length that can be probed in gravitational effective theories. It may be defined by the size of the minimal black…
The Emergent M-theory Limit
Ralph Blumenhagen, Niccolò Cribiori, Aleksandar Gligovic +1
It has been recently proposed that at each infinite distance limit in the moduli space of quantum gravity a perturbative description emerges with fundamental degrees of freedom giv…
Demystifying the Emergence Proposal
Ralph Blumenhagen, Niccolò Cribiori, Aleksandar Gligovic +1
We revisit the Emergence Proposal in the vector multiplet moduli space of type IIA N=2 supersymmetric string vacua in four dimensions, for which the string tree-level prepotential…
A note on modular invariant species scale and potentials
Niccolò Cribiori, Dieter Lust
The species scale provides an upper bound for the ultraviolet cutoff of effective theories of gravity coupled to a number of light particle species. We point out that modular invar…
Species Entropy and Thermodynamics
Niccolò Cribiori, Dieter Lust, Carmine Montella
We analyse particle species and the species scale in quantum gravity from a thermodynamic perspective. In close analogy to black hole thermodynamics, we propose that particle speci…
Supergravity EFTs and swampland constraints
Niccolò Cribiori, Fotis Farakos
In these proceedings, we review recent progress in analyzing the behavior of lower-dimensional supergravity theories when combined with swampland conjectures. We show that within s…
Quantum gravity constraints on scale separation and de Sitter in five dimensions
Niccolò Cribiori, Carmine Montella
We give evidence that supersymmetric anti-de Sitter vacua of five-dimensional supergravity cannot be scale separated as a consequence of quantum gravity constraints, such as the we…
On the correspondence between black holes, domain walls and fluxes
Niccolò Cribiori, Alessandra Gnecchi, Dieter Lust +1
We revisit and extend the correspondence between black holes, domain walls and fluxes in type IIA compactifications. We argue that these three systems can be described by the same…
The Scale of Supersymmetry Breaking and the Dark Dimension
Luis A. Anchordoqui, Ignatios Antoniadis, Niccolò Cribiori +2
We argue for a relation between the supersymmetry breaking scale and the measured value of the dark energy density . We derive it by combining two quantum gravity consistency sw…
Black hole entropy and moduli-dependent species scale
Niccolò Cribiori, Dieter Lust, Georgina Staudt
We provide a moduli-dependent definition of species scale in quantum gravity based on black hole arguments. Concretely, it is derived from of a lower bound on the entropy of extrem…
Dimensional Reduction of Cobordism and K-theory
Ralph Blumenhagen, Niccolò Cribiori, Christian Kneissl +1
It has been proposed that cobordism and K-theory groups, which can be mathematically related in certain cases, are physically associated to generalised higher-form symmetries. As a…
Dynamical Cobordism of a Domain Wall and its Companion Defect 7-brane
Ralph Blumenhagen, Niccolò Cribiori, Christian Kneissl +1
Starting from an already known solution in the literature, we study the dynamical cobordism induced by the backreaction of a non-supersymmetric, positive tension domain wall in str…
Looking for structure in the cobordism conjecture
David Andriot, Nils Carqueville, Niccolò Cribiori
The cobordism conjecture of the swampland program states that the bordism group of quantum gravity must be trivial. We investigate this statement in several directions, on both the…
