Scale-separated AdS vacua on Riemann-Flat Manifolds
Miquel Aparici, Ivano Basile, Bruno Valeixo Bento +1
Supergravity compactifications supported by fluxes and Casimir energy offer a simple strategy to concoct explicit, controlled and isolated vacua with parametric scale separation an…
Non-supersymmetric heterotic strings on
Ivano Basile, Daniel Robbins, Hassaan Saleem
We analyze the stability properties of a family of anti-de Sitter flux compactifications of the tachyon-free non-supersymmetric heterotic string in ten dimensions. In contrast with…
UV/IR relations from the worldsheet
Christian Aoufia, Ivano Basile, Giorgio Leone +1
We derive universal scaling relations for the low-energy effective action of string theory, connecting the vacuum energy and gauge couplings to higher-derivative Wilson coefficient…
Higher-Spin and Higher-Point Constraints on Stringy Amplitudes
Ivano Basile, Grant N. Remmen, Georgina Staudt
We employ multiparticle factorization to constrain deformations of tree-level open string amplitudes. Assuming minimal degeneracy among intermediate states of the same spin up thro…
Non-supersymmetric branes and discrete topological terms
Ivano Basile, Vittorio Larotonda
In a recent work, Tachikawa and Zhang proved the existence of a discrete topological term in the unique non-supersymmetric heterotic string with no tachyons in ten dimensions. This…
Dark bubble cosmology and the equivalence principle
Ivano Basile, Alessandro Borys, Joaquin Masias
The main goal of string phenomenology is to find realistic models of particle physics and cosmology within string theory. Dark bubble cosmology is an alternative to string compacti…
Instabilities in scale-separated Casimir vacua
Miquel Aparici, Ivano Basile, Nicolò Risso
Parametric scale separation is notoriously difficult to achieve in flux compactifications of gravitational effective theories. An appealing alternative to conventional Freund-Rubin…
Center Symmetry Breaking in Calabi--Yau Compactifications
Ivano Basile, Pouya Golmohammadi
It is widely believed that global symmetries must be broken in Quantum Gravity. This includes higher-form symmetries, which are commonplace in supergravity coupled to vector multip…
Corrections to the CRV pattern
Ivano Basile, Georgina Staudt
We investigate a pattern in the string landscape recently discovered by Castellano, Ruiz and Valenzuela, extending the analysis to subleading order in some calculable infinite-dist…
Dynamical dark energy in 0'B braneworlds
Ivano Basile, Alessandro Borys, Joaquin Masias
We build a novel realization of dark bubble cosmology in non-supersymmetric string theory. Among the simplest models in ten dimensions, the type 0'B orientifold is the unique optio…
Banks-Zaks Stabilisation of Non-SUSY Strings
Steven Abel, Ivano Basile, Viktor Matyas
It appears to be difficult within string theory to obtain genuine scale separation between spacetime and the internal sector. In this paper, we propose a novel mechanism for scale-…
Dark dimension with (little) strings attached
Ivano Basile, Dieter Lust
We motivate a relation between dark energy and the scale of new physics in weakly coupled string theory. This mixing between infrared and ultraviolet physics leads to a unique corn…
Species scale, worldsheet CFTs and emergent geometry
Christian Aoufia, Ivano Basile, Giorgio Leone
We study infinite-distance limits in the moduli space of perturbative string vacua. The remarkable interplay of string dualities seems to determine a highly non-trivial dichotomy,…
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…
Shedding black hole light on the emergent string conjecture
Ivano Basile, Dieter Lust, Carmine Montella
Asymptotically massless towers of species are ubiquitous in the string landscape when infinite-distance limits are approached. Due to the remarkable properties of string dualities,…
Shedding light on dark bubble cosmology
Ivano Basile, Ulf Danielsson, Suvendu Giri +1
Dark bubble cosmology is an alternative paradigm to compactification, which can circumvent issues of moduli stabilization and scale separation. In this paper we investigate how ele…
Anomaly constraints for heterotic strings and supergravity in six dimensions
Ivano Basile, Giorgio Leone
The landscape of six-dimensional supergravities is dramatically constrained by the cancellation of gauge and gravitational anomalies, but the full extent of its implications has no…
Global anomalies & bordism of non-supersymmetric strings
Ivano Basile, Arun Debray, Matilda Delgado +1
The three tachyon-free non-supersymmetric string theories in ten dimensions provide a handle on quantum gravity away from the supersymmetric lamppost. However, they have not been s…
Domain walls and distances in discrete landscapes
Ivano Basile, Carmine Montella
We explore a notion of distance between vacua of a discrete landscape that takes into account scalar potentials and fluxes via transitions mediated by domain walls. Such settings c…
A note on the admissibility of complex BTZ metrics
Ivano Basile, Andrea Campoleoni, Joris Raeymaekers
We perform a nontrivial check of Witten's recently proposed admissibility criterion for complex metrics. We consider the `quasi-Euclidean' metrics obtained from continuing the BTZ…
Infinite distances in multicritical CFTs and higher-spin holography
Ivano Basile, Andrea Campoleoni, Simon Pekar +1
We investigate the swampland distance conjecture in higher-spin gravity. To this end, we study multicritical generalizations of large- vector models, bosonic and fermionic, and…
Revisiting Dudas-Mourad compactifications
Ivano Basile, Salvatore Raucci, Sylvain Thomée
Superstring theories in ten dimensions allow spacetime supersymmetry breaking at the string scale at the expense of controlled Minkowski backgrounds. The next-to-maximally symmetri…
Emergent strings at infinite distance with broken supersymmetry
Ivano Basile
We investigate the infinite-distance properties of families of unstable flux vacua in string theory with broken supersymmetry. To this end, we employ a generalized notion of distan…
Supersymmetry Breaking and Stability in String Vacua: brane dynamics, bubbles and the swampland
Ivano Basile
We review some aspects of the dramatic consequences of supersymmetry breaking on string vacua. In particular, we focus on the issue of vacuum stability in ten-dimensional string mo…
