Abstract The tadpole conjecture proposes that complex structure moduli stabilisation by fluxes that have low tadpole charge can be realised only at special points in moduli space, leading generically to (large) gauge symmetries. Here we provide an ex

Abstract We propose an organizing principle for string theory moduli spaces in six dimensions with N $$ \mathcal{N} $$ = (1, 1), based on a rank reduction map, into which all known constructions fit. In the case of cyclic orbifolds, which are the mai

Abstract We derive a map relating the gauge symmetry groups of heterotic strings on T 4 to other components of the moduli space with rank reduction. This generalizes the results for T 2 and T 3 which mirror the singularity freezing mechanism of K3 su

Abstract We use a moduli space exploration algorithm to produce a complete list of maximally enhanced gauge groups that are realized in the heterotic string in 7d, encompassing the usual Narain component, and five other components with rank reduction

Abstract Compactifications of the heterotic string on special T d /ℤ2 orbifolds realize a landscape of string models with 16 supercharges and a gauge group on the left-moving sector of reduced rank d + 8. The momenta of untwisted and twisted states

Abstract 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 at special points in moduli space only to certain groups. We st

Abstract 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 pattern for generic tori, and scrutinize in full detail compact
