Moduli-Space Laplacians, Asymptotic Geometry, and the Emergent String Conjecture
Christian Aoufia, Muldrow Etheredge, Bernardo Fraiman +2
At asymptotic limits of moduli spaces of quantum gravity vacua, we argue that the masses of the lightest particle towers are eigenfunctions of the moduli-space Laplacian. The assoc…
Non-abelian asymmetric orbifolds with vanishing one-loop vacuum energy
Bernardo Fraiman, Vittorio Larotonda, Michelangelo Tartaglia
We present a partial classification of four-dimensional, non-supersymmetric Type II toroidal orbifolds with non-abelian point groups of rotations, and vanishing vacuum energy at on…
Non-supersymmetric dualities beyond the gauge algebra
Bernardo Fraiman, Vittorio Larotonda, Ling Lin +1
We provide a testing ground for dualities of non-supersymmetric type 0 orientifolds by finding the global forms of their gauge groups. As an example, we consider the Bergman--Gaber…
EFTs with Symmetric Moduli Spaces: the Landscape and the Swampland
Stephanie Baines, Veronica Collazuol, Bernardo Fraiman +2
The Swampland Distance Conjecture (SDC) states that, for any infinite-distance limit in the moduli space of a quantum gravity effective field theory (EFT), there should exist an in…
Symmetries and dualities in non-supersymmetric CHL strings
Bernardo Fraiman, Héctor Parra de Freitas
We chart the classical moduli space of heterotic strings with broken supersymmetry a la Scherk-Schwarz and gauge group rank reduced by 8 in eight dimensions. This space consists of…
The Boundary of Symmetric Moduli Spaces and the Swampland Distance Conjecture
Stephanie Baines, Veronica Collazuol, Bernardo Fraiman +2
For non-compact, locally symmetric moduli spaces M, the set of geodesics and the geometry of the boundary can be completely characterised using group theory. In particular, geodesi…
