Chern-Weil Global Symmetries and How Quantum Gravity Avoids Them
Ben Heidenreich, Jacob McNamara, Miguel Montero +3
We draw attention to a class of generalized global symmetries, which we call "Chern-Weil global symmetries," that arise ubiquitously in gauge theories. The Noether currents of thes…
Cobordism Conjecture, Anomalies, and the String Lamppost Principle
Miguel Montero, Cumrun Vafa
We consider consequences of triviality of cobordism classes and anomaly cancellation in supergravity theories in . We argue that this leads to the existence of certain defects…
de Sitter Bubbles and the Swampland
Alek Bedroya, Miguel Montero, Cumrun Vafa +1
A number of Swampland conjectures and in particular the Trans-Planckian Censorship Conjecture (TCC) suggest that de Sitter space is highly unstable if it exists at all. In this pap…
Nothing is certain in string compactifications
Iñaki García Etxebarria, Miguel Montero, Kepa Sousa +1
A bubble of nothing is a spacetime instability where a compact dimension collapses. After nucleation, it expands at the speed of light, leaving "nothing" behind. We argue that the…
A dS obstruction and its phenomenological consequences
Miguel Montero, Thomas Van Riet, Victoria Venken
In this note we observe that positive runaway potentials can generically be stabilized by abelian -form fluxes, leading to parametrically controlled de Sitter solutions after co…
