EFT (String) Tower Building
Alessandra Grieco, Ignacio Ruiz, Irene Valenzuela
We develop a bottom-up framework to reconstruct the asymptotic spectrum of light towers in four-dimensional effective field theories directly from their Kähler pote…

Bordisms between 9d type IIB supergravities and commutator widths of duality groups
Camilo las Heras, Ignacio Ruiz
We study the topological properties of bordisms interpolating between different 9d gauged supergravities obtained from compactification of type IIB string theory on …

A missing link: Brane networks and the Cobordism Conjecture
Markus Dierigl, Ignacio Ruiz
The absence of global symmetries in a quantum gravity theory often requires the introduction of (new) symmetry-breaking defects, which appear as singular objects in the low-energy…
