Description
Controlled de Sitter vacua, if they exist, seem to be hiding in difficult regions of the string Landscape -- they seem to require such an intricate interplay of ingredients, that many things can go wrong and invalidate the solutions. In fact, checking their validity with explicit computations is itself a difficult task. With this in mind, we explore a combination of ingredients that are both common and simple enough to be computed explicitly -- flat manifolds, fluxes and Casimir energies -- and could in principle provide de Sitter vacua in 3d and 4d.
