Dark energy, Ricci-nonflat spaces, and the swampland

Dark energy, Ricci-nonflat spaces, and the swampland

It was recently pointed out that the existence of dark energy imposes highly restrictive constraints on effective field theories that satisfy the Swampland conjectures. We provide a critical confrontation of these constraints with the cosmological framework emerging from the Salam-Sezgin model and i...
