TLDR
In this paper, the effective theory of Calabi-Yau compactifications with fluxes in type II theories is studied and the scalar potential for a generic electric Abelian gauging of the Heisenberg algebra, underlying all possible gaugings of R-R isometries, is presented and shown to exhibit, in some circumstances, a "dual" no-scale structure under the interchange of hypermultiplets and vector multiplets.About:

D-instantons and twistors
TL;DR: In this article, the effects of all D-instantons in Type II string compactifications on Calabi-Yau three-folds were derived by recasting the previously known A-type D2-instanton corrections in the language of contact geometry, covariantizing the result under electromagnetic duality, and using mirror symmetry.

SU(3) × SU(3) compactification and mirror duals of magnetic fluxes
Abstract: This paper analyses type II string theories in backgrounds which admit an SU(3) × SU(3) structure. Such backgrounds are designed to linearly realize eight out of the original 32 supercharges and as a consequence the low-energy effective action can be written in terms of couplings which are closely related to the couplings of four-dimensional N = 2 theories. This generalizes the previously studied case of SU(3) backgrounds in that the left- and right-moving sector each have a different globally defined spinor. Given a truncation to a finite number of modes, these backgrounds lead to a conventional four-dimensional low-energy effective theory. The results are manifestly mirror symmetric and give terms corresponding to the mirror dual couplings of Calabi-Yau compactifications with magnetic fluxes. It is argued, however, that generically such backgrounds are non-geometric and hence the supergravity analysis is not strictly valid. Remarkably, the naive generalization of the geometrical expressions nonetheless appears to give the correct low-energy effective theory.
