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…
Exploring the landscape of CHL strings on T^d
Anamaria Font, Bernardo Fraiman, Mariana Graña +2
Compactifications of the heterotic string on special T^d/Z_2 orbifolds realize a landscape of string models with 16 supercharges and a gauge group on the left-moving sector of redu…
Exploring the landscape of heterotic strings on T^d
Anamaría Font, Bernardo Fraiman, Mariana Graña +2
Compactifications of the heterotic string on T^d are the simplest, yet rich enough playgrounds to uncover swampland ideas: the U(1)^{d+16} left-moving gauge symmetry gets enhanced…
A new twist on heterotic string compactifications
Bernardo Fraiman, Mariana Graña, Carmen A. Núñez
A rich pattern of gauge symmetries is found in the moduli space of heterotic string toroidal compactifications, at fixed points of the T-duality transformations. We analyze this pa…
