Description
There is a candidate of string compactification background that has no Kähler moduli, which is the mirror of the rigid Calabi-Yau threefold. We studied Type IIB flux compactifications on the mirror space, corresponding to a T-dual of the DeWolfe-Giryavets-Kachru-Taylor model in Type IIA flux compactifications. The lack of Kähler deformations suggests it can be a suitable space for learning various Swampland conjectures by flux-based complex-structure moduli stabilizations. Indeed, we see that if we allow excessing D3 tadpole charge on the background, stable de Sitter vacua emerge. Although it is in the Swampland, we may clarify what control parameter characterizes the boundary between the landscape and the Swampland since there is almost no subtlety in the flux compactifications on the mirror of the rigid manifold. We may be able to examine further various Swampland conjectures by considering the background.
