Non-Geometric Heterotic Vacua from Type II Loci
Christian Aoufia, Giacomo Maggiorotti, Max Wiesner
We determine 4d heterotic string backgrounds dual to Type IIB string theory compactified on Calabi--Yau threefolds containing a type II locus in their complex s…
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…
Gravity Decoupling and Axionic Shift Symmetries
Christian Aoufia, Gonzalo F. Casas, Fernando Marchesano
We analyse the rôle of approximate axionic shift symmetries in gravity-decoupling limits arising in type II Calabi-Yau compactifications. Associated with each shift symmetry there…
UV/IR relations from the worldsheet
Christian Aoufia, Ivano Basile, Giorgio Leone +1
We derive universal scaling relations for the low-energy effective action of string theory, connecting the vacuum energy and gauge couplings to higher-derivative Wilson coefficient…
Laplacians in Various Dimensions and the Swampland
Christian Aoufia, Alberto Castellano, Luis Ibáñez
The species cutoff is a moduli-dependent quantity signaling the onset of quantum gravitational phenomena, whose form can be oftentimes determined from higher-derivative and higher-…
Species scale, worldsheet CFTs and emergent geometry
Christian Aoufia, Ivano Basile, Giorgio Leone
We study infinite-distance limits in the moduli space of perturbative string vacua. The remarkable interplay of string dualities seems to determine a highly non-trivial dichotomy,…
