Laplacians in Various Dimensions and the Swampland
Christian Aoufia, Alberto Castellano, Luis Ibáñez
The species cutoff is a moduli-dependent quantity signaling the onset of quantum gravitational phenomena, whose form can be oftentimes determined from higher-derivative and higher-…
Quantum Calabi-Yau Black Holes and Non-Perturbative D0-brane Effects
Alberto Castellano, Dieter Lüst, Carmine Montella +1
We compute the supersymmetric entropy of the most general BPS black hole in 4d supergravity coupled to vector multiplets obtained from Type IIA string theory…
Black Hole Entropy, Quantum Corrections and EFT Transitions
Alberto Castellano, Matteo Zatti
We revisit and study quantum corrections to the supersymmetric entropy of BPS black holes in 4d effective field theories (EFTs), which can be obtained from Type IIA…
The Quantum Gravity Scale and the Swampland
Alberto Castellano
This thesis investigates the role of the quantum gravity cut-off for effective field theories (EFTs) coupled to Einstein gravity, with an emphasis on its implications at low energi…
On the Species Scale, Modular Invariance and the Gravitational EFT expansion
Alberto Castellano, Alvaro Herráez, Luis E. Ibáñez
The concept of the species scale as the quantum gravity cut-off has been recently emphasised in the context of the Swampland program. Along these lines, we continue the quest for a…
Entropy Bounds and the Species Scale Distance Conjecture
José Calderón-Infante, Alberto Castellano, Alvaro Herráez +1
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…
Towers and Hierarchies in the Standard Model from Emergence in Quantum Gravity
Alberto Castellano, Álvaro Herráez, Luis E. Ibáñez
Based on Quantum Gravity arguments, it has been suggested that all kinetic terms of light particles below the UV cut-off could arise in the IR via quantum (loop) corrections. These…
The Emergence Proposal in Quantum Gravity and the Species Scale
Alberto Castellano, Alvaro Herráez, Luis E. Ibáñez
In the Emergence Proposal in QG it is conjectured that all light-particle kinetic terms are absent in the fundamental UV theory and are generated by quantum corrections in the IR.…
IR/UV Mixing, Towers of Species and Swampland Conjectures
Alberto Castellano, Alvaro Herráez, Luis E. Ibáñez
By applying the Covariant Entropy Bound (CEB) to an EFT in a box of size one obtains that the UV and IR cut-offs of the EFT are necessarily correlated. We argue t…
A Gravitino Distance Conjecture
Alberto Castellano, Anamaría Font, Alvaro Herraez +1
We conjecture that in a consistent supergravity theory with non-vanishing gravitino mass, the limit is at infinite distance. In particular one can write $M_{…
