On the Origin of Species Thermodynamics and the Black Hole - Tower Correspondence
Alvaro Herráez, Dieter Lüst, Joaquin Masias +1
Species thermodynamics has been proposed in analogy to black hole thermodynamics. The entropy scales like an area and is given by the mere counting of the number of the species. In…

The Double EFT Expansion in Quantum Gravity
José Calderón-Infante, Alberto Castellano, Alvaro Herráez
In this work, we aim to characterize the structure of higher-derivative corrections within low-energy Effective Field Theories (EFTs) arising from a UV-complete theory of quantum g…

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…
