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…
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…
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…
