On scale separation in type II AdS flux vacua
Anamaría Font, Alvaro Herráez, Luis E. Ibáñez
We study the separation of AdS and Kaluza-Klein (KK) scales in type II 4d AdS orientifold vacua. We first address this problem in toroidal/orbifold type IIA vacua with metric fluxe…

The Swampland Distance Conjecture and Towers of Tensionless Branes
Anamaría Font, Alvaro Herráez, Luis E. Ibáñez
The Swampland Distance Conjecture states that at infinite distance in the scalar moduli space an infinite tower of particles become exponentially massless. We study this issue in t…

A Strong Scalar Weak Gravity Conjecture and Some Implications
Eduardo Gonzalo, Luis E. Ibáñez
We propose a new version of the scalar Weak Gravity Conjecture (WGC) which would apply to any scalar field coupled to quantum gravity. For a single scalar it is given by the differ…
