We propose a variant of the KKLT (A)dS flux vacuum construction which does not require an antibrane to source the volume modulus. The strategy is to find nonzero local minima of the no-scale potential in the complex structure and dilaton directions in moduli space. The corresponding no-scale potential expanded about this point sources the volume modulus in the same way as does the antibrane of the KKLT construction. We exhibit explicit examples of such nonzero local minima of the no-scale potential in a simple toroidal orientifold model.

Flux compactifications in string theory: A Comprehensive review (2005, background): “Other uplifting mechanisms involve adding D7-brane fluxes [190]; starting with a local nonzero minimum of the no-scale potential (which does depend on the overall volume through the factor eK) and expanding around it [191]; Let us review here the KKLT uplifting procedure.”

What if string theory has no de Sitter vacua? (2018, methodology): “An alternative method to uplift uses the AISD components of the 3-form fluxes since these would add positive energy and have a similar powerlaw dependence on the volume modulus [79].”
Large-volume flux compactifications: Moduli spectrum and D3/D7 soft supersymmetry breaking (2005, background): “The original proposal involved anti D3 brane tensions [3], but one could also use magnetic field fluxes on D7 branes which correspond to D-terms [20], or IASD fluxes generating F-terms [21].”
Emergence of spontaneously broken supersymmetry on an anti-D3-brane in KKLT dS vacua (2014, background): “In these models the effective supergravity action is manifestly supersymmetric, whereas dS vacua break supersymmetry spontaneously, on solutions, as in early dS models of this type in [25].”
Gaugino Condensation and Nonperturbative Superpotentials in Flux Compactifications (2004, background): “Alternatively, one can simply start in a vacuum of the no-scale potential which is at positive V , and play off the tadpole for Kähler moduli against the nonperturbative corrections [15].”
Inflating in a Better Racetrack (2006, methodology): “Alternatively, this same lifting could be obtained by turning on magnetic fluxes on the D7 branes, and using the resulting Fayet-Iliopoulos D-term potential to raise the value of the potential at its minimum [25], again leading to a result of the form of eq.”
