Heterotic-Type II duality in the hypermultiplet sector
Jan Louis, Roberto Valandro
We revisit the duality between heterotic string theory compactified on K3 x T^2 and type IIA compactified on a Calabi-Yau threefold X in the hypermultiplet sector. We derive an exp…
Moduli Stabilisation for Chiral Global Models
Michele Cicoli, Christoph Mayrhofer, Roberto Valandro
We combine moduli stabilisation and (chiral) model building in a fully consistent global set-up in Type IIB/F-theory. We consider compactifications on Calabi-Yau orientifolds which…
G-flux in F-theory and algebraic cycles
Andreas P. Braun, Andres Collinucci, Roberto Valandro
We construct explicit G4 fluxes in F-theory compactifications. Our method relies on identifying algebraic cycles in the Weierstrass equation of elliptic Calabi-Yau fourfolds. We sh…
