Universal Pattern in Quantum Gravity at Infinite Distance / Castellano, Alberto (Madrid, Autonoma U. ; Madrid, IFT) ; Ruiz, Ignacio (Madrid, Autonoma U. ; Madrid, IFT) ; Valenzuela, Irene (Madrid, IFT ; Madrid, Autonoma U. ; CERN)
Quantum gravitational effects become significant at a cut-off species scale that can be much lower than the Planck scale whenever we get a parametrically large number of fields becoming light. This is expected to occur at any perturbative limit of an effective field theory coupled to gravity, or equivalently, at any infinite distance limit in the field space of the quantum gravity completion. [...]

Stringy Evidence for a Universal Pattern at Infinite Distance / Castellano, Alberto (Madrid, IFT) ; Ruiz, Ignacio (Madrid, IFT) ; Valenzuela, Irene (Madrid, IFT ; CERN)
Infinite distance limits in the moduli space of a quantum gravity theory are characterized by having infinite towers of states becoming light, as dictated by the Distance Conjecture in the Swampland program. These towers imply a drastic breakdown in the perturbative regimes of the effective field theory at a quantum gravity cut-off scale known as the species scale. [...]

Entropy Bounds and the Species Scale Distance Conjecture / Calderón-Infante, José (CERN) ; Castellano, Alberto (U. Autonoma, Madrid (main)) ; Herráez, Alvaro (IPhT, Saclay) ; Ibáñez, Luis E. (U. Autonoma, Madrid (main))
The Swampland Distance Conjecture (SDC) states that, as we move towards an infinite distance point in moduli space, a tower of states becomes exponentially light with the geodesic distance in any consistent theory of Quantum Gravity. Although this fact has been tested in large sets of examples, it is fair to say that a bottom-up justification that explains both the geodesic requirement and the exponential behavior has been missing so far.
