Abstract
We propose an uplift mechanism using a structure of multi-Kahler moduli dependence in the F-term potential of type IIB string theory compactifications. This mechanism requires a D-term condition that fixes one modulus to be proportional to another modulus, resulting in a trivial D-term potential. De Sitter minima are realized along with an enhancement of the volume in the Large Volume Scenario and no additional suppression of the uplift term such as warping is required. We further show the possibility to realize the uplift mechanism in the presence of more Kahler moduli such that we expect the uplift mechanism to work in many other compactifications.

In the case of h1+,1 = 3 this corresponds to a two Kahler moduli Large Volume Scenario (LVS) potential plus an uplift term that allows de Sitter (dS) vacua as we will show in section 2.3.1 Note that in general all required D7-brane stacks have to be consistent with possible factorizations of the Whitney brane that cancels the O7 charge [58, 59]
We have proposed an uplift mechanism using the structure of at least two small Kahler moduli Tb and Tc in Swiss-Cheese type compactifications
Summary
We illustrate the uplift mechanism by a D-term generated racetrack in Calabi-Yaus with the following properties: there are two small 4-cycles and two linear combinations of these small cycles that are rigid such that the existence of two non-perturbative terms is guaranteed in the superpotential avoiding additional fermionic zero modes from cycle deformations or Wilson lines. We show that this setup in general allows to stabilize the moduli in a dS vacuum at large volume
