Scale-separated AdS vacua on Riemann-Flat Manifolds

Miquel Aparici, Ivano Basile, Bruno Valeixo Bento +1

Supergravity compactifications supported by fluxes and Casimir energy offer a simple strategy to concoct explicit, controlled and isolated vacua with parametric scale separation an…

A maximum in M-theory from Casimir energies on Riemann-flat manifolds

Miquel Aparici, Bruno Valeixo Bento, Miguel Montero

We describe a fully explicit, four-dimensional, top-down de Sitter saddle, constructed via compactification of M-theory on the Riemann-flat manifold . The solutio…

What IIB looks IIA string: String Cobordisms via Non-Compact CFTs

Edoardo Anastasi, Miguel Montero, Angel M. Uranga +1

The Swampland Cobordism Conjecture predicts the existence of end-of-the-world branes for every consistent Quantum Gravity theory, and domain walls connecting the Landscape. A pertu…

Asymmetric orbifolds with vanishing one-loop vacuum energy

Vittorio Larotonda, Miguel Montero, Michelangelo Tartaglia

We present a systematic study of non-supersymmetric type II toroidal asymmetric orbifolds with vanishing vacuum energy at one-loop in string perturbation theory. These are engineer…

Cobordism Utopia: U-Dualities, Bordisms, and the Swampland

Noah Braeger, Arun Debray, Markus Dierigl +2

The U-dualities of maximally supersymmetric supergravity theories lead to celebrated non-perturbative constraints on the structure of quantum gravity. They can also lead to the pre…

Exotic supergravities and the Swampland

Miguel Montero, Michelangelo Tartaglia

In six dimensions, there is an exotic supermultiplet that contains only fields of spin , but no graviton, and that on a circle reduces to 5D $\mathcal{N…
